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…
Discovery of a variable multi-phase outflow in the X-ray-emitting tidal disruption event ASASSN-20qc
P. Kosec, D. Pasham, E. Kara +1
Tidal disruption events (TDEs) are exotic transients that can lead to temporary super-Eddington accretion onto a supermassive black hole. Such accretion mode is naturally expected…
Target of Opportunity Observations of Gravitational Wave Events with LSST
R. Margutti, P. Cowperthwaite, Z. Doctor +79
The discovery of the electromagnetic counterparts to the binary neutron star merger GW170817 has opened the era of GW+EM multi-messenger astronomy. Exploiting this breakthrough req…
Characterization of a peculiar Einstein Probe transient EP240408a: an exotic gamma-ray burst or an abnormal jetted tidal disruption event?
B. O'Connor, D. Pasham, I. Andreoni +30
We present the results of our multi-wavelength (X-ray to radio) follow-up campaign of the Einstein Probe transient EP240408a. The initial 10 s trigger displayed bright soft X-ray (…
The complex time and energy evolution of quasi-periodic eruptions in eRO-QPE1
R. Arcodia, G. Miniutti, G. Ponti +8
Quasi-periodic eruptions (QPEs) are recurrent X-ray bursts found so far in the nuclei of low-mass galaxies. Their trigger mechanism is still unknown, but recent models involving on…
The destruction and recreation of the X-ray corona in a changing-look Active Galactic Nucleus
C. Ricci, E. Kara, M. Loewenstein +16
We present the drastic transformation of the X-ray properties of the active galactic nucleus 1ES 1927+654, following a changing-look event. After the optical/UV outburst the power-…
