The early afterglow of GRB 190829A
S. Dichiara, E. Troja, V. Lipunov +19
GRB 190829A at z=0.0785 is the fourth closest long GRB ever detected by the Neil Gehrels Swift observatory, and the third confirmed case with a very high energy component. We prese…
Identification of an X-ray Pulsar in the BeXRB system IGR J182191347
B. O'Connor, E. Gogus, D. Huppenkothen +25
We report on observations of the candidate Be/X-ray binary IGR J182191347 with \textit{Swift}/XRT, \textit{NuSTAR}, and \textit{NICER} during Type-I outbursts in March and June…
Constraints on the electromagnetic counterpart of the Neutron Star Black Hole merger GW200115
S. Dichiara, R. L. Becerra, E. A. Chase +10
We report the results of our follow-up campaign for the neutron star - black hole (NSBH) merger GW200115 detected during the O3 run of the Advanced LIGO and Advanced Virgo detector…
A month of monitoring the new magnetar Swift J1555.2-5402 during an X-ray outburst
Teruaki Enoto, Mason Ng, Chin-ping Hu +23
The soft gamma-ray repeater Swift J1555.2-5402 was discovered by means of a 12-ms duration short burst detected with Swift BAT on 2021 June 3. Then 1.6 hours after the first burst…
The Fast Radio Burst FRB 20201124A in a star forming region: constraints to the progenitor and multiwavelength counterparts
L. Piro, G. Bruni, E. Troja +16
We present the results of a multiwavelength campaign of FRB 20201124A, the third closest repeating fast radio burst recently localized in a nearby (z=0.0978) galaxy. Deep VLA obser…
Kilonova Detectability with Wide-Field Instruments
Eve A. Chase, Brendan O'Connor, Christopher L. Fryer +7
Kilonovae are ultraviolet, optical, and infrared transients powered by the radioactive decay of heavy elements following a neutron star merger. Joint observations of kilonovae and…
Late-time radio observations of the short GRB200522A: constraints on the magnetar model
G. Bruni, B. O'Connor, T. Matsumoto +4
GRB200522A is a short duration gamma-ray burst (GRB) at redshift =0.554 characterized by a bright infrared counterpart. A possible, although not unambiguous, interpretation of t…
Accurate flux calibration of GW170817: is the X-ray counterpart on the rise?
E. Troja, B. O'Connor, G. Ryan +7
X-ray emission from the gravitational wave transient GW170817 is well described as non-thermal afterglow radiation produced by a structured relativistic jet viewed off-axis. We sho…
Probing the reach of the Intermediate Polar Cataclysmic Variable Population with Swift J183920.1-045350
Nicholas M. Gorgone, Patrick A. Woudt, David Buckley +18
We report on the Swift/XRT Deep Galactic Plane Survey discovery and multi-wavelength follow-up observations of a new intermediate polar Cataclysmic Variable, Swift J183920.1-045350…
Evidence of extended emission in GRB 181123B and other high-redshift short GRBs
S. Dichiara, E. Troja, P. Beniamini +7
We study the high-energy properties of GRB 181123B, a short gamma-ray burst (sGRB) at redshift 1.75. We show that, despite its nominal short duration with 2 s, t…
A tale of two mergers: constraints on kilonova detection in two short GRBs at z0.5
B. O'Connor, E. Troja, S. Dichiara +15
We present a detailed multi-wavelength analysis of two short Gamma-Ray Bursts (sGRBs) detected by the Neil Gehrels Swift Observatory: GRB 160624A at and GRB 200522A at $z…
