Temporal and Spectral Properties of the Persistent Radio Source Associated with FRB 20190520B with the VLA

The Astrophysical Journal, 2023
Among more than 800 known fast radio bursts (FRBs), only two, namely FRB 20121102A and FRB 20190520B, are confirmed to be associated with persistent radio sources (PRSs).

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

The Radio Transient Sky [PDF]

, 2013
Radio transients are known on time scales from nanoseconds to years, from sources in the Galaxy and beyond, and with either coherent or incoherent emission mechanisms.

Transient radio bursts from rotating neutron stars

, 2006
The radio sky is relatively unexplored for transient signals, although the potential of radio-transient searches is high. This was demonstrated recently by the discovery of a previously unknown type of source, varying on timescales of minutes to hours ...

Low-frequency, Wideband Study of an Active Repeater, FRB 20240114A, with the GMRT

The Astrophysical Journal
We report the detection of 167 bursts from an active repeater, FRB 20240114A, using the upgraded Giant Metrewave Radio Telescope. The observations were carried out over a frequency range of 300–750 MHz, and on four different dates over a period of 6 ...

A New Radio Detection of the Transient Bursting Source GCRT J1745−3009

The Astrophysical Journal, 2006
GCRT J1745-3009 is a transient bursting radio source located in the direction of the Galactic center, discovered by Hyman et al. in 330 MHz VLA observations from 2002 September 30-October 1. We have searched for bursting activity from GCRT J1745-3009 in nearly all of the available 330 MHz VLA observations of the Galactic center since 1989, as well as ...

Limits on Fast Radio Bursts and other transient sources at 182 MHz using the Murchison Widefield Array [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We present a survey for transient and variable sources, on timescales from 28 seconds to $\sim$1 year, using the Murchison Widefield Array (MWA) at 182 MHz. Down to a detection threshold of 0.285 Jy, no transient candidates were identified, making this the most constraining low-frequency survey to date and placing a limit on the surface density of ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

A 22-yr southern sky survey for transient and variable radio sources using the Molonglo Observatory Synthesis Telescope [PDF]

Monthly Notices of the Royal Astronomical Society, 2011
We describe a 22-year survey for variable and transient radio sources, performed with archival images taken with the Molonglo Observatory Synthesis Telescope (MOST). This survey covers $2775 \unit{deg^2}$ of the sky south of $δ< -30\degree$ at an observing frequency of 843 MHz, an angular resolution of $45 \times 45 \csc | δ| \unit{arcsec^2}$ and a ...

Polarization Characteristics of the Hyperactive FRB 20240114A

The Astrophysical Journal Supplement Series
Fast radio bursts (FRBs) are transient radio bursts of extragalactic origin characterized by millisecond durations and high luminosities. We report on observations of FRB 20240114A conducted with the Robert C.
