Detection of the 2021 Outburst of RS Ophiuchi with the LST-1
Yukiho Kobayashi, Arnau Aguasca-Cabot, María Isabel Bernardos Martín +2
Novae are luminous explosions in close binaries which host a white dwarf and a companion donor star. They are triggered by a thermonuclear runaway when the white dwarf accretes a c…
LST-1 observations of an enormous flare of BL Lacertae in 2021
Seiya Nozaki, Katsuaki Asano, Juan Escudero +2
The first prototype of LST (LST-1) for the Cherenkov Telescope Array has been in commissioning phase since 2018 and already started scientific observations with the low energy thre…
The Second Catalog of Interplanetary Network Localizations of Konus Short Duration Gamma-Ray Bursts
D. Svinkin, K. Hurley, A. Ridnaia +72
We present the catalog of Interplanetary Network (IPN) localizations for 199 short-duration gamma-ray bursts (sGRBs) detected by the Konus-Wind (KW) experiment between 2011 January…
Cosmological Fast Optical Transients with the Zwicky Transient Facility: A Search for Dirty Fireballs
Anna Y. Q. Ho, Daniel A. Perley, Yuhan Yao +33
Dirty fireballs are a hypothesized class of relativistic massive-star explosions with an initial Lorentz factor below the required to pro…
The lowest frequency Fast Radio Bursts: Sardinia Radio Telescope detection of the periodic FRB 180916 at 328 MHz
M. Pilia, M. Burgay, A. Possenti +35
We report on the lowest-frequency detection to date of three bursts from the fast radio burst FRB 180916, observed at 328 MHz with the Sardinia Radio Telescope (SRT). The SRT obser…
An embedded X-ray source shines through the aspherical AT2018cow: revealing the inner workings of the most luminous fast-evolving optical transients
Raffaella Margutti, B. D. Metzger, R. Chornock +41
We present the first extensive radio to gamma-ray observations of a fast-rising blue optical transient (FBOT), AT2018cow, over its first ~100 days. AT2018cow rose over a few days t…
Gamma-Ray Observations of Nova Sgr 2015 No. 2 with INTEGRAL
Thomas Siegert, Alain Coc, Laura Delgado +11
INTEGRAL observed the nova V5668 Sgr around the time of its optical maximum on March 21, 2015. Studies at UV wavelengths showed spectral lines of freshly produced Be-7. This could…
INTEGRAL Detection of the First Prompt Gamma-Ray Signal Coincident with the Gravitational Wave Event GW170817
V. Savchenko, C. Ferrigno, E. Kuulkers +20
We report the e INTernational Gamma-ray Astrophysics Laboratory (INTEGRAL) detection of the short gamma-ray burst GRB 170817A (discovered by Fermi-GBM) with a signal-to-noise ratio…
iPTF16asu: A Luminous, Rapidly-Evolving, and High-Velocity Supernova
L. Whitesides, R. Lunnan, M. M. Kasliwal +23
Wide-field surveys are discovering a growing number of rare transients whose physical origin is not yet well understood. Here, we present optical and UV data and analysis of iPTF16…
Two giant outbursts of V 0332+53 observed with INTEGRAL
C. Ferrigno, L. Ducci, E. Bozzo +7
In July 2015, the high-mass X-ray binary V 0332+53 underwent a giant outburst, a decade after the previous one. This system hosts a strongly magnetized neutron star. During the 200…
Imprint of a 2 Myr old source on the cosmic ray anisotropy
V. Savchenko, M. Kachelriess, D. V. Semikoz
We study numerically the anisotropy of the cosmic ray (CR) flux emitted by a single source calculating the trajectories of individual CRs. We show that the contribution of a single…
GRB 120711A: an intense INTEGRAL burst with long-lasting soft gamma-ray emission and a powerful optical flash
A. Martin-Carrillo, L. Hanlon, M. Topinka +20
A long and intense gamma-ray burst (GRB) was detected by INTEGRAL on July 11 2012 with a duration of ~115s and fluence of 2.8x10^-4 erg cm^-2 in the 20 keV-8 MeV energy range. GRB…
GRB 130925A: an ultra-long Gamma Ray Burst with a dust-echo afterglow, and implications for the origin of the ultra-long GRBs
P. A. Evans, R. Willingale, J. P. Osborne +24
GRB 130925A was an unusual GRB, consisting of 3 distinct episodes of high-energy emission spanning 20 ks, making it a member of the proposed category of `ultra-long' bursts.…
A Missing-Link in the Supernova-GRB Connection: The Case of SN 2012ap
Sayan Chakraborti, Alicia Soderberg, Laura Chomiuk +50
Gamma Ray Bursts (GRBs) are characterized by ultra-relativistic outflows, while supernovae are generally characterized by non-relativistic ejecta. GRB afterglows decelerate rapidly…
GRB 080407: an ultra-long burst discovered by the IPN
V. Pal'shin, K. Hurley, J. Goldsten +25
We present observations of the extremely long GRB 080704 obtained with the instruments of the Interplanetary Network (IPN). The observations reveal two distinct emission episodes,…
