Evidence for a Compact Object in the Aftermath of the Extra-Galactic Transient AT2018cow
Dheeraj R. Pasham, Wynn C. G. Ho, William Alston +16
The brightest Fast Blue Optical Transients (FBOTs) are mysterious extragalactic explosions that may represent a new class of astrophysical phenomena. Their fast time to maximum bri…
The Gamow Explorer: A gamma-ray burst observatory to study the high redshift universe and enable multi-messenger astrophysics
N. E. White, F. E. Bauer, W. Baumgartner +63
The Gamow Explorer will use Gamma Ray Bursts (GRBs) to: 1) probe the high redshift universe (z > 6) when the first stars were born, galaxies formed and Hydrogen was reionized; and…
Reverberation in tidal disruption events: dust echoes, coronal emission lines, multi-wavelength cross-correlations, and QPOs
Sjoert van Velzen, Dheeraj R. Pasham, Stefanie Komossa +2
Stellar tidal disruption events (TDEs) are typically discovered by transient emission due to accretion or shocks of the stellar debris. Yet this luminous flare can be reprocessed b…
X-ray Quasi-Periodic Eruptions from two previously quiescent galaxies
R. Arcodia, A. Merloni, K. Nandra +21
Quasi-Periodic Eruptions (QPEs) are extreme high-amplitude bursts of X-ray radiation recurring every few hours and originating near the central supermassive black holes in galactic…
The 450 days X-ray monitoring of the changing-look AGN 1ES 1927+654
C. Ricci, M. Loewenstein, E. Kara +16
1ES 1927+654 is a nearby active galactic nucleus (AGN) which underwent a changing-look event in early 2018, developing prominent broad Balmer lines which were absent in previous ob…
Rapid accretion state transitions following the tidal disruption event AT2018fyk
Thomas Wevers, Dheeraj R. Pasham, Sjoert van Velzen +7
Following a tidal disruption event (TDE), the accretion rate can evolve from quiescent to near-Eddington levels and back over months - years timescales. This provides a unique oppo…
