The JCMT Transient Survey: Single-epoch Transients and Variability of Faint Sources

open access: yesThe Astrophysical Journal, 2022
Abstract Short-duration flares at millimeter wavelengths provide unique insights into the strongest magnetic reconnection events in stellar coronae and combine with longer-term variability to introduce complications to next-generation cosmology surveys.

A New Sample of Transient Ultraluminous X-Ray Sources Serendipitously Discovered by Swift/XRT

open access: yesThe Astrophysical Journal, 2023
Ultraluminous X-ray sources (ULXs) are our best laboratories for studying extreme super-Eddington accretion. Most studies of these objects are of relatively persistent sources; however, there is growing evidence to suggest a large fraction of these ...

A transient placental source of serotonin for the fetal forebrain [PDF]

open access: yesNature, 2011
Serotonin (5-hydroxytryptamine or 5-HT) is thought to regulate neurodevelopmental processes through maternal-fetal interactions that have long-term mental health implications. It is thought that beyond fetal 5-HT neurons there are significant maternal contributions to fetal 5-HT during pregnancy but this has not been tested empirically.

Steady-state visual evoked potentials can be explained by temporal superposition of transient event-related responses [PDF]

open access: yes, 2011
<p><b>Background:</b> One common criterion for classifying electrophysiological brain responses is based on the distinction between transient (i.e. event-related potentials, ERPs) and steady-state responses (SSRs).

Neutrino Echoes from Multimessenger Transient Sources [PDF]

open access: yesPhysical Review Letters, 2019
The detection of the high-energy neutrino event, IceCube-170922A, demonstrated that multimessenger particle astrophysics triggered by neutrino alerts is feasible. We consider time delay signatures caused by secret neutrino interactions with the cosmic neutrino background and dark matter and suggest that these can be used as a novel probe of neutrino ...

Cosmic ray anisotropies from transient extragalactic sources [PDF]

open access: yes, 2021
We study the spectrum and anisotropies of ultrahigh energy cosmic ray transient sources, accounting for the effects of their propagation through the turbulent extragalactic magnetic fields.

VARIABLE AND TRANSIENT RADIO SOURCES IN THE FIRST SURVEY [PDF]

open access: yesThe Astrophysical Journal, 2011
A comprehensive search for variable and transient radio sources has been conducted using ~55,000 snapshot images of the FIRST survey. We present an analysis leading to the discovery of 1,627 variable and transient objects down to mJy levels over a wide range of timescales (few minutes to years).
