report on behalf of the Les Makes, Abastumani, Lisnyky and GRANDMA
collaborations.
We performed galaxy-targeted observations of the LIGO/Virgo S190425z
event (GCN #24168) with the Les Makes-T60 telescope located in La
Reunion-France, Abastumani-T70 telescope located in Abastumani
Astrophysical Observatory, and AZT-8 telescope located in Observational
Station Lisnyky of TSNU of Kyiv.
The target galaxies are selected from the list of potential host
galaxies from the GLADE catalog in the 90% credible area of the
localization region of the LIGO/Virgo GW event. Note that these galaxies
are compatible within 3 sigma for the distance given by GW event.
The list of the galaxies we observed is shown in the tables below.
TStart and TEnd refers respectively to the time of the first and last
exposure for a given galaxy. Observations are not necessarily continuous
in this interval.
Les Makes-T60 cm imaged 52 galaxies in clear filter. The observation
started on 04/25/19 15:18:10 UTC which corresponds approximately to 421
minutes after the GW trigger time. The typical limiting magnitude is
19.2 for a 180 s exposure.
