Radio observations of tidal disruption events (TDEs) probe material ejected by the disruption
of stars by supermassive black holes (SMBHs), uniquely tracing the formation and evolution …

Several long-period radio transients have recently been discovered, with strongly polarized
coherent radio pulses appearing on timescales between tens to thousands of seconds,. In …

In the era of the SKA precursors, telescopes are producing deeper, larger images of the sky
on increasingly small time-scales. The greater size and volume of images place an …

Astronomical surveys of celestial sources produce streams of noisy time series measuring
flux versus time ('light curves'). Unlike in many other physical domains, however, large (and …

It has been known for half a century that the interstellar medium (ISM) of our Galaxy is
structured on scales as small as a few hundred kilometers, more than 10 orders of …

We have performed a search over 3440 deg 2 of Epoch 1 (2017–2019) of the Very Large
Array Sky Survey to identify unobscured quasars in the optical (0.2< z< 3.2) and obscured …

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 half …

We have commenced a multiyear program, the Caltech-NRAO Stripe 82 Survey (CNSS), to
search for radio transients with the Jansky VLA in the Sloan Digital Sky Survey Stripe 82 …

Coherent radio bursts detected from M dwarfs have some analogy with solar radio bursts but
reach orders of magnitude higher luminosities. These events trace particle acceleration …

The Variables and Slow Transients Survey (VAST) on the Australian Square Kilometre Array
Pathfinder (ASKAP) is designed to detect highly variable and transient radio sources on …
