New @LIGOMagazine out this week!
Natalie Williams (@cosmic_bae_) from @UoBIGWaves chats with Jess Irwin (@cosmo__jess) about being on parameter estimation rota during #ObservingRun4.

Read online at (pdf): ligo.org/magazine/LIGO-magaz…
In #ObservingRun4, collaboration members volunteer on the parameter estimation rota.
In our latest #LIGOMagazine, Natalie Williams (@cosmic_bae_, @UoBIGWaves) & Jessica Irwin (@cosmo__jess, @uofgravity) tell us more!

We are delighted to have been named a University of Sanctuary - awarded to institutions which commit to providing a welcoming and supportive environment for asylum seekers and refugees.
A thread 🧵👇
From all of us at @UoBIGWaves many congratulations to Prof. Mike Cruise who's been awarded an OBE. Mike initiated gravitational wave research at @unibirmingham @eps_unibham back in late 90s. Ultimately, if @UoBIGWaves exists, we owe it to him.
Congratulations to Professor Adrian ‘Mike’ Cruise, Emeritus Professor of Astrophysics and Space Research at @unibirmingham, who has been awarded an OBE in the 2024 New Year Honours:

Our @unibirmingham researchers are supporting the development of the next-gen gravitational wave detectors. The detectors will help astronomers probe the furthest reaches of the cosmos:

The IPTA gravitational wave analysis group just finished a comparison of the PTA (@NANOGrav @EPTAGW @InPTA_GW) results published this past summer. You can read all about it here: arxiv.org/abs/2309.00693 🧵

Paper day! :partying_face: In work by Piero Rettegno (@INFN_), Geraint Pratten @grntprttn, Lucy M. Thomas @gravywavylucy, Patricia Schmidt @p_g_schmidt (all @UOBIGWaves) and Thibault Damour (@Institut_IHES), we produce numerical simulations of black hole scattering 💫...
ALT Plot of analytical predictions (in coloured solid and dashed lines) compared to numerical results represented by black dots, for effective aligned spin (chi effective) on the x-axis, against scattering angle theta on the y-axis. The solid blue curve labelled 4PM w^eob shows excellent agreement with the numerical results.
And BBC wanted to talk more with @hannahmidd8 this morning, but they kept her in the waiting room. Just what you need after working around the clock for weeks...
Earlier this week, Hannah Middleton (@hannahmidd8) from @UoBIGWaves @unibirmingham and Michael Keith from @OfficialUoM @UoMNews were at @jodrellbank talking to @BBCPallab about pulsar timing arrays!

Our @EPTAGW @InPTA_GW #GravitationalWaves results are out arxiv.org/abs/2306.16214. CPTA has ~4.5sigma (wow!), @CSIRO_ATNF PPTA ~2sigma. @NANOGrav somewhere in-between. Lots of work to understand how this all adds up.

Two years ago, leaders of @InPTA_GW , @EPTAGW , @NANOGrav , and the PPTA (@CSIRO_ATNF) signed an agreement to coordinate a synchronous publication of results from their individual PTA data sets. This agreement, known as the “3P+ agreement”, will come to fruition on June 29th.
Alberto Vecchio retweeted
We teamed up with @EPTAGW and combined our data with theirs for our latest venture!
Keep an eye out on this space on 29th June as we coordinate the release of our exciting science results with @nanograv, @CSIRO_ATNF and @ARC_OzGRav and @CPTA

👀 Keep an eye out for some exciting news from PTA collaborations across the globe, including researchers from @UoBIGWaves @unibirmingham!
On June 29th, pulsar timing array (PTA) collaborations around the globe will present new results. For updates on the announcement of the @NANOGrav collaboration (which I belong to), check out our web site: nanograv.org/news/2023Announ…

EPTA and InPTA are releasing their latest results on Thursday 29 June, in coordination with other PTAs around the world @InPta @ARC_OzGRav @CSIRO_ATNF @NANOGrav

#OTD in 2015, the universe’s gravitational waves, predicted by Albert Einstein a century before, were observed for the first time by @LIGO.
The observation led to a new way to study our universe and the 2017 #NobelPrize in Physics for Rainer Weiss, Barry Barish and Kip Thorne.
We are hiring at @UoBIGWaves @eps_unibham. Faculty positions covering instrumentation, observations and theory across #GravitationalWaves and #MultiMessenger astronomy: jobregister.aas.org/ad/0f853…

Watch our President Prof Sheila Rowan, speak on @BBCNews about why physics is for everyone and what the @PhysicsNews research and evidence suggests #physics #IOPLimitLess
Congratulations @mattnicholl56 !
Huge congratulations to Dr Matt Nicholl, recipient of the @RoyalAstroSoc's Fowler Award for early career achievements in astronomy.

The IPTA DR2 #GravitationalWaves background paper is out arxiv.org/abs/2201.03980. Evidence for common ultra-low frequency stochastic signal consistent with previous EPTA, @NANOGrav and PPTA results. No sign (yet) of Hellings-Downs correlation

#NASAWebb is safely in space with its solar array drawing power from the Sun! Its reaction wheels will keep the spacecraft pointed in the right direction so that its sunshield can protect the telescope from radiation and heat: blogs.nasa.gov/webb/2021/12/…
#UnfoldTheUniverse
Quite a crowd of black holes and neutron stars... the universe seems to be pretty efficient in producing these binaries, and now we can routinely detect them! Huge amount of work from so many people at @UoBIGWaves as part of @LIGO @ego_virgo @KAGRA_PR #GWTC3 activities
We have exciting news! We've just released our new @LIGO @ego_virgo @KAGRA_PR catalog #GWTC3,which includes many more detections from the 2nd part of #O3 and brings our total number of #GravitationalWaves events to 90. Read all about #GWTC3 at ligo.org/detections/O3bcatal…
