Look out for an upcoming paper where Margaret shows (with contributions also from @MariosKalomen and myself) how to use observations of beyondGR physics to make new cosmological measurements using only GW observations 🙂

[LIGO @LIGO]

How do we learn about black holes from gravitational waves? Key properties leave fingerprints in the gravitational-wave signal. This infographic from the LIGO Magazine explains more

Kicking off Thursday @APSMeetings with an engaging session on Population Inference of Gravitational Wave Sources!

First up, @ColmMTalbot presenting an alternative, entropy-based approach to standard hierarchical inference working directly with strain instead of posterior samples

[Event Horizon 'Scope @ehtelescope]

Breaking news: the Event Horizon Telescope team unveils strong magnetic fields spiraling at the edge of Milky Way’s central black hole, Sagittarius A*. This new image suggests that strong magnetic fields may be common to all black holes.

We're now half-way through our 2 week engineering run. On 3 April, we should start the second part of our fourth observing run (O4b)

We have enjoyed a few stretches with @LIGOWA @LIGOLA and @ego_virgo observing together! Here's a plot of performance on Saturday

[NCfA @NevadaCfA]

The last session in the @NevadaCfA symposium will focus on future observations

[NCfA @NevadaCfA]

Starting the final day of the @NevadaCfA symposium with a session covering the many physical processes governing the multimessenger observations we are looking for.

[NCfA @NevadaCfA]

Starting the afternoon session of the @NevadaCfA symposium, focusing on electromagnetic astrophysical transients

[NCfA @NevadaCfA]

We're now going for the second day of the 2024 @NevadaCfA symposium!
The first section of the day will focus on Gravitational Wave Astrophysics.

[NCfA @NevadaCfA]

The afternoon session will focus on Neutrino Astrophysics.

[NCfA @NevadaCfA]

Very excited for this year's @NevadaCfA multimessenger astrophysics symposium at @UNLVMuseum!

[Dark Energy Survey @theDESurvey]

We've released our final analysis of the expansion of the Universe using Type Ia Supernovae!! Read about the hard work of our many supernovae scientists over the past several years.

We're not done yet! More results to come using other probes in 2024.

[Marios Kalomenopoulos @MariosKalomen]

@alemelk @WKCosmo Hi! Would it be possible to share any papers on that?

[Marios Kalomenopoulos @MariosKalomen]

@skdh Statistically speaking, this argument doesn't make sense.

[Marios Kalomenopoulos @MariosKalomen]

@cosmosquark @srrappoccio IMO, this is the main problem of most documents like this. Well intended, but the main focus is on *individual* "solutions", while the climate change problem is hugely social/political, i.e. very large scale!

@skdh Very interesting! Thanks 👍
