ZTF DR1 light curves of SNe Type Ia
Type Ia supernovae (SNe Ia) in the nearby Hubble flow are excellent distance indicators in cosmology. The Zwicky Transient Facility (ZTF) has observed a large sample of SNe from... -
Blazars study with ZTF DR6 and Roma-BZCAT
We investigate the temporal and colour variability of 897 blazars, comprising 455 BL Lacertae objects (BL Lacs) and 442 Flat Spectrum Radio Quasars (FSRQs), selected from the... -
Variable sources from HST in the JWST NEP TDF
The James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-domain Field (TDF) is a >14' diameter field optimized for multiwavelength time-domain science with JWST.... -
ELEPHANT Hostless AstroNomical Transients
Transient astronomical events that exhibit no discernible association with a host galaxy are commonly referred to as hostless. These rare phenomena can offer unique insights... -
Galactic DM contribution to the extragalactic FRBs
We provide an empirical list of the Galactic dispersion measure (DM_Gal_) contribution to the extragalactic fast radio bursts (FRBs) along 72 sightlines. It is independent of... -
Rapidly evolving transients discovered by DES
Rapidly evolving transients (RETs), also termed fast blue optical transients, are a recently discovered group of astrophysical events that display rapid luminosity evolution.... -
Gaia counterparts to GW events
The recent discoveries of gravitational wave events and in one case also its electromagnetic (EM) counterpart allow us to study the Universe in a novel way. The increased... -
LIGO and Virgo third observing run with GRANDMA
We present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA). The network consists of 21 telescopes with both photometric and spectroscopic... -
Photometry & spectroscopy follow-up of ASASSN-20hx
We present observations of ASASSN-20hx, a nearby ambiguous nuclear transient (ANT) discovered in NGC 6297 by the All-Sky Automated Survey for Supernovae (ASAS-SN). We observed... -
Swift/BAT 14-195keV obs. of FRB 180916.J0158+65
FRB 180916.J0158+65 is one of the nearest, periodically repeating, and actively bursting fast radio bursts (FRBs) that has been localized to the outskirts of a spiral galaxy. In... -
HST imaging and light curves of 21 SPIRITS variables
The SPitzer InfraRed Intensive Transients Survey (SPIRITS) searched for luminous infrared (IR) transients and variables in nearly 200 nearby galaxies from 2014 to 2019, using... -
UV, optical and X-ray evolution of ASASSN-14ko
ASASSN-14ko is a recently discovered periodically flaring transient at the center of the active galactic nucleus (AGN) ESO 253-G003 with a slowly decreasing period. Here, we... -
Fast-evolving SNIbn with LCO LCs & FLOYDS sp.
Rapidly evolving transients, or objects that rise and fade in brightness on timescales two to three times shorter than those of typical Type Ia or Type II supernovae (SNe), have... -
Transients in the centers of PS & QBS galaxies
Tidal disruption events (TDEs) have been found to show a preference for post-starburst (PS) and quiescent Balmer-strong (QBS) galaxies. This preference can be used to help find... -
Additional bursts at 1.4GHz for FRB 121102
We present an analysis of a densely repeating sample of bursts from the first repeating fast radio burst, FRB 121102. We reanalyzed the data used by Gourdji+... -
DES DR1 galaxies in the field of FRB 180924
Fast radio burst (FRB) dispersion measures (DMs) record the presence of ionized baryons that are otherwise invisible to other techniques enabling resolution of the matter... -
Fast-transients confirmed by ZTFReST & LCs
The most common way to discover extragalactic fast transients, which fade within a few nights in the optical, is via follow-up of gamma-ray burst and gravitational-wave... -
ZTF photometric measurements of AT 2018lqh
We report on the discovery of AT 2018lqh (ZTF 18abfzgpl)-a rapidly evolving extragalactic transient in a star-forming host at 242Mpc. The transient g-band light curve's duration...
