LSXPS Swift-XRT point sources and transients
We present the Living Swift-XRT Point Source (LSXPS) catalogue and real-time transient detector. This system allows us for the first time to carry out low- latency searches for... -
Light curves & spectra of two giant M dwarf flares
We present time-series optical spectroscopy of two stellar flares with complex multi-peaked light curves: a 2.1_-.3_^+.4^x10^34^erg flare from an M8 ultra-cool dwarf, and a... -
X-ray & opt. light curves of XTE J1859+226
Using the Zwicky Transient Facility, in 2021 February we identified the first known outburst of the black hole X-ray transient XTE_J1859+226 since its discovery in 1999. The... -
Finding tidal disruption event & flares in ZTF
Transient accretion events onto supermassive black holes (SMBHs), such as tidal disruption events (TDEs), Bowen Fluorescence Flares (BFFs), and active galactic nuclei (AGNs),... -
Bursts from FAST obs. of FRB 20220912A in 2022
We report the observations of FRB 20220912A using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We conducted 17 observations totaling 8.67hr and detected a... -
X-ray burst associated to FRB200428 with Insight-HXMT
A double-peak X-ray burst from the Galactic magnetar SGR J1935+2154 was discovered to be associated with the two radio pulses of FRB200428 separated by 28.97+/-0.02ms. Precise... -
AT 2021loi photometry & sp. follow-up
The optical-ultraviolet transient AT 2021loi is located at the center of its host galaxy. Its spectral features identify it as a member of the Bowen fluorescence flare (BFF)... -
SN2019wxt follow-up
We present optical, radio, and X-ray observations of a rapidly evolving transient SN2019wxt (PS19hgw), discovered during the search for an electromagnetic counterpart to the... -
Neutrino events in the direction of ICECAT-1 alerts
Beginning in 2016, the IceCube Neutrino Observatory has sent out alerts in real time containing the information of high-energy (E>~100TeV) neutrino candidate events with... -
X-ray/UV & optical evolution of ASASSN -14ko
ASASSN-14ko is a nuclear transient at the center of the AGN ESO253-G003 that undergoes periodic flares. Optical flares were first observed in 2014 by the All-Sky Automated... -
Extragalactic fast blue optical transients from ZTF
We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above... -
LCs and sp. of 30 ZTF TDEs
Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the... -
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... -
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... -
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... -
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...
