The ZTF Source Classification Project: III. A Catalog of Variable Sources
Brian F. Healy, Michael W. Coughlin, Ashish A. Mahabal +22
The classification of variable objects provides insight into a wide variety of astrophysics ranging from stellar interiors to galactic nuclei. The Zwicky Transient Facility (ZTF) p…
Ready for O4 II: GRANDMA Observations of Swift GRBs during eight-weeks of Spring 2022
I. Tosta e Melo, J. -G. Ducoin, Z. Vidadi +106
We present a campaign designed to train the GRANDMA network and its infrastructure to follow up on transient alerts and detect their early afterglows. In preparation for O4 II camp…
A 12.4 day periodicity in a close binary system after a supernova
Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37
Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…
Chemical Distribution of the Dynamical Ejecta in the Neutron Star Merger GW170817
Shreya Anand, Peter T. H. Pang, Mattia Bulla +11
GW170817 and its associated electromagnetic counterpart AT2017gfo continue to be a treasure trove as observations and modeling continue. Recent precision astrometry of AT2017gfo wi…
: A Multi-input Convolutional Neural Network to Automate and Expedite Bright Transient Identification for the Zwicky Transient Facility
Nabeel Rehemtulla, Adam A. Miller, Michael W. Coughlin +1
The Bright Transient Survey (BTS) relies on visual inspection ("scanning") to select sources for accomplishing its mission of spectroscopically classifying all bright extragalactic…
A data science platform to enable time-domain astronomy
Michael W. Coughlin, Joshua S. Bloom, Guy Nir +50
SkyPortal is an open-source software package designed to efficiently discover interesting transients, manage follow-up, perform characterization, and visualize the results. By enab…
GRANDMA and HXMT Observations of GRB 221009A -- the Standard-Luminosity Afterglow of a Hyper-Luminous Gamma-Ray Burst
D. A. Kann, S. Agayeva, V. Aivazyan +113
GRB 221009A is the brightest Gamma-Ray Burst (GRB) detected in more than 50 years of study. In this paper, we present observations in the X-ray and optical domains after the GRB ob…
Bayesian model selection for GRB 211211A through multi-wavelength analyses
Nina Kunert, Sarah Antier, Vsevolod Nedora +12
Although GRB 211211A is one of the closest gamma-ray bursts (GRBs), its classification is challenging because of its partially inconclusive electromagnetic signatures. In this pape…
