Interpreting the afterglow of a black hole’s breakfast - Technology Org

An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of astronomers.

A sample of active black holes at the centre of 136 galaxies were found to shine in microwave and X-ray light in the same way, no matter their appetite for the surrounding galactic matter like clouds of gas and dust.

Led by scientists at Cardiff University, the team says the process is not predicted by our current understanding of how black holes eat.

Currently understood to be intrinsically different depending on their appetites, active black holes are characterised by the layout of their cores and the way they draw in galactic matter.

However, the team found these black holes may have more similarities than previously thought.

Their findings, published in Monthly Notices of the Royal Astronomical Society: Letters, could offer new information about how galaxies evolve.

Lead author, Dr Ilaria Ruffa, a postdoctoral research associate at Cardiff University’s School of Physics and Astronomy, said: “The microwave and X-ray glow we detect from the regions around these black holes seems to relate to their mass directly and to originate from extremely hot puffy streams of gas falling into them.

“This is the case in both systems that have huge appetites that eat nearly an entire star like our Sun per year, and those with lesser appetites that eat the same amount of material over 10 million years.

“This was very surprising because we had previously thought that such streams should occur only in systems eating at low rates. In those with huge appetites, the gas feeding the black hole should collapse into a disc, usually called `the accretion disc’, allowing the system to be fed more ordered.”

The team discovered while investigating the link between the cold gas around active black holes and how these are fuelled in the WISDOM sample of 35 nearby galaxies captured by the Atacama Large Millimeter/submillimeter Array (ALMA) of telescopes in Chile.

The correlations observed by the team also provide a new method for estimating the masses of black holes – something astronomers believe is central to understanding their impact on the evolution of galaxies across the Universe.

Co-author Dr Timothy Davis, a Reader in Cardiff University’s School of Physics and Astronomy, added: “Galaxies care very much about the black holes that exist within their cores. And they probably shouldn’t because, while we always think of black holes as these super massive beasts consuming everything around them, they are really very small and lightweight in the context of an entire galaxy. “And yet they have a mysterious non-gravitational influence over material tens of thousands of light years away from them. This is something we have puzzled over as astronomers for many years.”

Catch ‘Em All | Dec 28, 2020 | Loop Sessions

Time to cut to the chase: fuck 2020! Time to join in on a much anticipated gathering to see this year out, once and for all!

Loop Sessions 52, the last of the year, is gearing up to be the spiciest edition yet (I mean just look at Shogo‘s latest flyer y’all)! While that may be hard to believe with the previous session including the likes of a shape-shifting Vincent Stephen-Ong of Urban Science (who provided the LS 51 crate by way of their quarantine-inspired music challenge #PassLeBeat), and the soulful soundscapes of Sabrina Sabotage and others, I am hoping to finally see more of the Timon-esque ramblings of LS’s shmings (who can also be heard on podcast Lasers on the Ride), and I heard there would be a special after-Loops Twitch stream? You’ll have to tune in this Wednesday to find out. The beats, the jokes, the chat shenanigans: gotta catch ’em all!

More Great Agile Debates, Part 1

My previous presentations and blogs on "Great Agile Debates" have proven extremely popular, so I thought I would add to this body of knowledge with a new blog series. In each blog, I will cover five more great agile debates for your consideration. Keep in mind that my opinions are my own, and not necessarily those of any other organization I am affiliated with. I'd also love to hear what you think, so don't be shy - leave some comments, and let's debate! Here are the first five topics of debate about agile I will cover: - The Developers are a Sub-team in Scrum - The Three Questions are Required - A Product Goal is Not Required - Backlog Refinement is an Official Scrum Event - Teams Cannot Combine Different Agile Elements

The Developers are a Sub-team in Scrum

This is now FALSE! In previous versions of The Scrum Guide, the Developers were considered a sub-team within a Scrum Team, but in the 2020 update to the guide, this concept was removed. The point of this change was to ensure that the team is a cohesive whole – without having a team within a team. The former Dev Team concept created an “us versus them” attitude between the Developers, the Scrum Master, and the Product Owner. Going forward as one united team, many things that were once in the domain of the Dev Team are now jointly owned responsibilities among the entire Scrum Team.

Further, having everyone on the Scrum Team on equal footing as team members allows people to collaborate and build trust more easily. Everyone on the team should be “in the know” on what’s happening, without any surprises from the separateness of having a sub-team.

The Three Questions are Required

This, too, is now FALSE! In the previous versions of The Scrum Guide, the three questions were, in fact, the prescribed format for running the Daily Scrum. As a reminder, the questions were: - What did I do yesterday that helped the Development Team meet the Sprint Goal? - What will I do today to help the Development Team meet the Sprint Goal? - Do I see any impediment that prevents me or the Development Team from meeting the Sprint Goal? The creators of the guide realized that requiring the answers to these three questions was far too prescriptive. Their goal was to simplify the framework. Many Scrum Teams had already stopped using the three questions because it felt rote and repetitive. Answering these questions didn’t really give the team the real opportunity to figure out their collective plan for the day toward accomplishing the Sprint Goal.

I myself had already stopped using this format on my Scrum Team. A far better exercise is to “walk the board” – going through your Sprint Backlog and looking at each item (either by person or from top to bottom) and its progress. Having this visual also helps to identify if there are any impediments, whether some team members are overloaded while others might not have much to do. There are other options, as well. The main idea is that you can choose the format that works best for your team in your context. Some teams prefer to post on a collaboration channel like Slack or Teams, while others simply go round robin verbally, without focusing on what has already happened – rather, looking forward to what needs to be accomplished today.

A Product Goal is Not Required

You guessed it – WRONG! A Product Goal is now required. Prior versions of The Scrum Guide did not include this concept. In the absence of this as a requirement of Scrum, many teams and Product Owners introduced their own idea to fill the void: Product Vision. Some people might argue that there is little difference between a vision and a goal. I struggle with this myself, especially having trained many Product Owners and helped them craft Product Vision Statements.

In training new Product Owners, I now feel obligated to include the Product Goal as it is now an official aspect of Scrum. The way I see it, these can be two separate things. The vision is the aspirational description of what the product is and how it is beneficial, which is strategic in nature. On the other hand, the Product Goal (or goals) is more tactical, with specific measurable objectives similar to SMART goals. These provide more direction on what is needed to achieve the vision.

Backlog Refinement is an Official Scrum Event

Sorry, folks! This one isn’t true, either (at least not yet). While The Scrum Guide infers that Backlog Refinement is an important, ongoing activity, it’s not an officially recognized Scrum event. Personally, I would like to see this added as an “official” requirement of the Scrum Framework. To be successful in any type of endeavor using Scrum, whether project- or product-based, having a properly managed Product Backlog is essential.

Many teams only do this activity on an ad-hoc basis, which is inconsistent and unpredictable. I prefer to have this activity, if running two-week sprints, on the opposite day from the Sprint Review. This ensures that Backlog Refinement actually happens regularly. I would also suggest a timebox similar to that of the Sprint Planning event. These events are very similar, but Backlog Refinement is a preliminary opportunity for the team to review and discuss upcoming stories, answer any open questions, and gain a shared understanding of each item. The team can also use this session to size the stories. Having done this work in advance also speeds up Sprint Planning.

Teams Cannot Combine Different Agile Elements

Once more, FALSE! There is no rule written that people cannot combine different aspects of various agile practices. Most Scrum Teams also use Kanban boards, and other concepts borrowed from lean, XP, or other agile frameworks. Scrum alone isn’t always sufficient to create all products or solve all business problems. Support teams, for example, would be much better suited toward sticking with Kanban, but may also use Scrum activities such as periodic retrospectives to look for improvement opportunities. Likewise, traditionally run projects (aka waterfall), can also benefit from inserting some agile ideas into their projects. They too may have more frequent retrospectives, rather than end-of-project Lessons Learned (when it’s too late to do anything about it).

For teams that want to avoid full-blown scaling, they might simply take from the Nexus scaling framework (or others) to achieve some parts of scaled agile, without adding too much additional overhead and cost. The Project Management Institute also offers a certification in Disciplined Agile, which I would call a compilation of all kinds of agile ideas, that can be combined in whatever fashion makes sense and works for your team.

Wrapping it Up
