Swift-BAT GUANO follow-up of gravitational-wave triggers in the third LIGO-Virgo-KAGRA observing run
Gayathri Raman, Samuele Ronchini, James Delaunay +1819
We present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network usin…
An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz
M. Nicholl, T. Wevers, S. R. Oates +42
At 66 Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and iPTF16fnl. Its proximity all…
Dramatic change in the boundary layer in the symbiotic recurrent nova T Coronae Borealis
G. J. M. Luna, K. Mukai, J. L. Sokoloski +6
A sudden increase in the rate at which material reaches the most internal part of an accretion disk, i.e. the boundary layer, can change its structure dramatically. We have witness…
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Multiwavelength picture of the blazar S5 0716+714 during its brightest outburst
Marina Manganaro, Giovanna Pedaletti, Marlene Doert +24
S5 0716+714 is a well known BL Lac object, one of the brightest and most active blazars. The discovery in the Very High Energy band (VHE, E > 100 GeV) by MAGIC happened in 2008. In…
SOUSA: the Swift Optical/Ultraviolet Supernova Archive
Peter J. Brown, Alice A. Breeveld, Stephen Holland +2
The Ultra-Violet Optical Telescope on the Swift spacecraft has observed hundreds of supernovae, covering all major types and most subtypes. Here we introduce the Swift Optical/Ultr…
Ultraviolet Observations of Super-Chandrasekhar Mass Type Ia Supernova Candidates with Swift UVOT
Peter J. Brown, Paul Kuin, Richard Scalzo +6
Among Type Ia supernovae (SNe~Ia) exist a class of overluminous objects whose ejecta mass is inferred to be larger than the canonical Chandrasekhar mass. We present and discuss the…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
A panchromatic view of the restless SN2009ip reveals the explosive ejection of a massive star envelope
R. Margutti, D. Milisavljevic, A. M. Soderberg +54
The 2012 explosion of SN2009ip raises questions about our understanding of the late stages of massive star evolution. Here we present a comprehensive study of SN2009ip during its r…
G306.3-0.9: A newly discovered young galactic supernova remnant
Mark Reynolds, Shyeh Loi, Tara Murphy +14
We present X-ray and radio observations of the new Galactic supernova remnant (SNR) G306.3-0.9, recently discovered by Swift. Chandra imaging reveals a complex morphology, dominate…
The Long-Lived UV "Plateau" of SN 2012aw
Amanda J. Bayless, Tyler Pritchard, Peter W. A. Roming +9
Observations with the Swift UVOT have unambiguously uncovered for the first time a long-lived, UV "plateau" in a Type II-P supernova (SN). Although this flattening in slope is hint…
Panchromatic observations of the textbook GRB 110205A: constraining physical mechanisms of prompt emission and afterglow
W. Zheng, R. F. Shen, T. Sakamoto +56
We present a comprehensive analysis of a bright, long duration (T90 ~ 257 s) GRB 110205A at redshift z= 2.22. The optical prompt emission was detected by Swift/UVOT, ROTSE-IIIb and…
