Search For a Counterpart to the Subsolar Mass Gravitational Wave Candidate S251112cm
Nicholas Vieira, Noah Franz, Bhagya Subrayan +49
The recent candidate gravitational-wave (GW) alert from a compact object merger involving at least one subsolar mass (SSM) object has prompted questions about their origins. S25111…
Optical observations of candidate host galaxies of eight fast X-ray transients
Agnes P. C. van Hoof, Peter G. Jonker, Lieke Tommel +15
Fast X-ray transients (FXTs) are extragalactic flashes of X-rays with a typical duration of minutes to hours for which a variety of origins has been proposed and observed. To decip…
ODIN: Searching for LyC emission from Lyman- emitters at in the E-COSMOS and XMM-LSS fields
Eunsuk Seo, Hyunmi Song, Lucia Guaita +18
We investigated Lyman-continuum (LyC) emission from Lyman- emitters (LAEs) at , identified in the One-hundred-deg DECam Imaging in Narrowbands (ODIN) survey. Of the…
The Open mulTiwavelength Transient Event Repository (OTTER): Infrastructure Release and Tidal Disruption Event Catalog
Noah Franz, Kate D Alexander, Sebastian Gomez +10
Multiwavelength analyses of astrophysical transients are essential for understanding the physics of these events. To make such analyses more efficient and effective, we present the…
Resolving the Nuclear Environments of Tidal Disruption Event Host Galaxies within 45 pc
Megan Newsome, Iair Arcavi, K. Decker French +5
Using HST/STIS observations, we present the highest-spatial-resolution spectroscopic study to date of four tidal disruption event (TDE) host galaxies, with the best observed being…
The intermediate-mass black hole 2XMM J123103.2+110648: a varying disc accretion rate during possible X-ray quasi-periodic eruptions?
Z. Cao, P. G. Jonker, S. Wen +2
We fit the evolving X-ray spectra of the variable and fading source 2XMM J123103.2+110648 (J1231), which is an intermediate-mass black hole (IMBH) candidate. Recent X-ray timing st…
