In case any of you are in the Monterey, CA area: This Saturday, 14 April, I will give a free public lecture on the "Dance of Dwarf Galaxies" and possible implications for Dark Matter.

Time: 7:30pm
Place: Monterey Peninsula College, Lecture Forum #102

mira.org/events.htm
This is organized by MIRA, the "Monterey Institute for Research in Astronomy", which has an interesting history: In 1972, a bunch of @CWRUastro grad students decided to rather start their own institute instead of going through the usual job market. mira.org/museum/story.h…
They raised funds, chose a site for an observatory, and apparently even got the army to build a road to the site for free, as a training exercise. en.wikipedia.org/wiki/Craig_Che…
Curiously, MIRA has two connections to my career: I also worked at @CWRUastro, and the first conference I ever attended in the U.S. was held in Monterey. So I couldn't say no when they invited me to give a talk (thought I have to admit that I had not heard of them before).

Not everybody seems to realize it, but working on Dark Matter alternatives such as MOND requires a lot of knowledge: you have to understand not only that theory, but also it’s more popular alternative, and the successes and challenges faced by both (or more) approaches.
None of these approaches is without issues, but we all tend to weight different lines of evidence differently. Thing is, if you don’t know much about MOND, it is easily dismissed. But that’s a quite subjective reason.
If you work on MOND, though, you are in a constant debate about its feasibility and all the evidence in favor of Dark Matter. That’s not only with colleagues, you are debating yourself all the time.

So, our paper on LCDM predictions for the Radial Acceleration Relation of dwarf satellite galaxies, lead by @enreecog, was recently accepted for publication in PRL.
And today, @UniBonn (my alma mater) published a press release on this work: uni-bonn.de/news/164-2018?…
Here’s the link to the just published article: journals.aps.org/prl/abstract/1…

Finally read this nice preprint by Forero-Romero & Arias: arxiv.org/abs/1805.03188…
They use an interesting approach to measure the overall asphericity of the distribution of the top 11 to 15 satellites around the MW and M31, and use it to compare to cosmological simulations.
One of the paper's main finding is that the MW system is highly exceptionally flattened. Similar satellite arrangements are rare in LCDM simulations. This agrees with what I've been saying, so for me this is reassuring, though not super exciting.
Their most exciting finding is buried in the text: they report that hydrodynamical cosmological simulations result in *less* flattened satellite systems than dark-matter only sims.

So much for "baryons solve the satellite plane problem".

I'll be doing some minor tweeting for #AstroBowl. I am on the @OSUPhysics and @OSUAstro faculty, a member of @osuccapp , and a 2002 graduate of the @uwastronomy and UW physics (why no twitter?) departments. Stay tuned for more about my group, @HowWeScience !
TBH, I have no idea when the game starts today. My husband and son are out at @COSI today, I'll be setting up my course website (intro E&M for engineers) while tweeting.
I am a physicist who uses the tools of theoretical physics and astronomy to learn about the fundamental physics of dark matter. What is dark matter? #AstroBowl (1/N)

Dark Matter Hunters Pivot After Years of Failed Searches - WIRED

“Pivot” is an interesting choice of words. Sorta implies that one is pivoting from one thing (WIMPS) to something else. In which case the “something else” needs to be specified. apple.news/AfFMHcOI9QlK8e…
The whole dark matter search community reminds me of Daffy Duck in the episode quoted from IMDb here. [shockingly, I do not instantly find a gif of Daffy falling off said cliff.]
Reading this article does not inspire confidence. Sounds more like they’re poised to make the same mistakes all over again. Having spent decades in a fruitless search for WIMPs motivated by the WIMP miracle - an irrelevant numerical coincidence - might they decide to learn more?

Bent on growth, Zuck & Sandberg ignored warning signs about their platform being used by Russia and then sought to conceal them from public view.
nytimes.com/2018/11/14/tec…
This report is based on interviews w more than 50 current & former Fb execs & employees, lawmakers, govt officials, lobbyists & congressional staff members. Most spoke on the condition of anonymity because they had signed NDAs, were not authorized, or feared retaliation.
At critical moments over the last three years, Sandberg & Zuck were distracted by personal projects, and passed off security and policy decisions to subordinates, according to current and former executives.

PM Abiy smiles when asked how the liberalization of the Airlines and Electric Corporation would provide better services to the #Ethiopia|n public. He says, “we are in debt, we have to pay back but we can’t. And secondarily, we aren’t able to finish projects we have started."
#Ethiopia: Live "The target is to create a market-led capitalist system. The private sector is crucial to help us develop this capitalist system. This is because the private sector is better at being profitable than the government.”
PM Abiy
On the airlines:“African leaders want one airlines for the whole continent. This was one of the points of the economic integration. Following this, EAL has bought Malawi’s half airlines, and also Zambia’s AL, and also of Chad’s and Guinea, Togo. We will be buying more shares."

Time to go through and list all of the followers I found interesting based entirely on their bios from reading my 'follower' list. This decision has come about after a vote, which won 19-0. There is no electoral college on Twitter, so the popular vote always wins. Here we go!
This list also goes from "the oldest follower" to "the newest follower", just so that you know. If you have been ignored, then you need a more outstanding bio.
.@DeplorableMedia is a news media website dedicated to being pro-Trump, to the point that there are two sections to the website - "Real News" and "Trump News".

... My God, maybe they mean that the Trump News is fake news?

If you want a news website anyway, here you go.
