A Broadband X-ray Analysis and Optical Counterpart Search of IC5052 ULX
Nabil Brice, Dominic J. Walton, Felix Fürst +10
We present broadband X-ray spectral and timing analysis of the Ultra-luminous X-ray source (ULX) in IC5052 using simultaneous XMM-Newton and NuSTAR observations from 2022, suppleme…
Optimal Follow-Up of Gravitational-Wave Events with the UltraViolet EXplorer (UVEX)
Leo P. Singer, Alexander W. Criswell, Sydney C. Leggio +10
The UltraViolet EXplorer (UVEX) is a wide-field ultraviolet space telescope selected as a NASA Medium-Class Explorer (MIDEX) mission for launch in 2030. UVEX will undertake deep, c…
Electromagnetic Follow-up to Gravitational Wave Events with the UltraViolet EXplorer (UVEX)
Alexander W. Criswell, Sydney C. Leggio, Michael W. Coughlin +9
The Ultraviolet Explorer (UVEX) is expected to fly in 2030 and will have the opportunity -- and the rapid near/far ultraviolet (UV) capabilities -- to glean unprecedented insight i…
The long-term variability of a population of ULXs monitored by Chandra
Hannah P. Earnshaw, Gauri Patti, Murray Brightman +5
We present preliminary results of a Chandra Large Program to monitor the ultraluminous X-ray source (ULX) populations of three nearby, ULX-rich galaxies over the course of a year,…
Return to the forgotten ULX: a broadband NICER+NuSTAR study of NGC 4190 ULX-1
Hannah P Earnshaw, Matteo Bachetti, Murray Brightman +7
We observed the nearby and relatively understudied ultraluminous X-ray source (ULX) NGC 4190 ULX-1 jointly with NICER and NuSTAR to investigate its broadband spectrum, timing prope…
