@LIGO @ego_virgo @KAGRA_PR @LIGOWA @LIGOLA Boom! @LIGOWA, @LIGOLA and @ego_virgo all observing! #O3IsHere
@LIGO @ego_virgo @KAGRA_PR Welcome to O3b! We are now observing. Come on @LIGOWA! #O3IsHere
@LIGO @hannahmidd8 My article in the @LIGO Magazine on living in the era of public alerts for our gravitational-wave candidates www.ligo.org/magazine/LIGO-magazine-i... It is certainly exciting, even if the candidates don't work out as detections! #O3ishere
The latest edition of the @LIGO Magazine is out! https://www.ligo.org/magazine/ This issue is looking at all the exciting progress from our third observing run (O3) including our new public alerts of gravitational-wave candidates #O3ishere
The probabilities for the different source classes fold in the current uncertainties on rates the different classes. Since we've not seen some of the classes before, these probabilities could change a lot after we get more events. Stay tuned #O3IsHere
tuned #O3IsHere
#ICYMI: We've had an exciting start to our @LIGO–@ego_virgo observing run. Lovely article from @RyanFMandelbaum gizmodo.com/gravitational-wave-detec... I hope you're as excited as we are #O3IsHere
In our first two observing runs, we found that the detectors typically ran better at night, when it is quieter. This could mean that waking up US time to a new detection candidate becomes a regular occurrence #O3IsHere
With the EHT M87 black hole picture and the third observing run of LIGO and Virgo, this will be the Year of Black Holes!

Black holes are exciting, but not so promising if you want to see things with telescopes. If you did want to follow-up an alert NED has a handy cross-referencing with galaxies http://ned.ipac.caltech.edu/gwf/events #O3IsHere
We expect binary black holes to be our most common source. Given our past detection rate and our improved sensitivity, we're looking at ~5–40 detections across O3! (There may be more alerts as not all will pan out) #O3IsHere
From some quick (and so not perfect) estimates, it doesn't look like this signal matches something with low masses: PROB_NS = 0.00, so there's probably nothing to see; PROB_BBH = 1.00, it's probably a binary black hole. Not too surprising #O3IsHere

@LIGO & @ego_virgo have currently set a preliminary notice
https://gcn.gsfc.nasa.gov/notices_l/S190408an.lvc
Currently the event is being reviewed, and it may be retracted if there's anything suspicious #O3IsHere
Here is #GravitationalWave candidate 190408an https://gracedb.ligo.org/superevents/S190408an/view/ #O3IsHere
Potential binary black hole candidate

To mark the start of O3, we have another #HumanofLIGO! It's none other than Nobel Prize Winner Barry Barish! Check out his quote:
