Radio Emission of Nearby Early-type Galaxies in the Low and Very Low Radio Luminosity Range

The Astrophysical Journal, 2023
We analyze radio continuum emission of early-type galaxies with dynamical measurements of central supermassive black hole (SMBH) masses and well-characterized large-scale environments, but regardless of the exact level of the nuclear activity.

HII Region Ionization of the Interstellar Medium: A Case Study of NGC 7538 [PDF]

, 2016
Using data from the Green Bank Telescope, we analyze the radio continuum (free-free) and radio recombination line (RRL) emission of the compact HII region NGC 7538 (Sharpless 158).

The Close AGN Reference Survey (CARS): An Interplay between Radio Jets and AGN Radiation in the Radio-quiet AGN HE0040-1105

The Astrophysical Journal, 2023
We present a case study of HE 0040-1105, an unobscured radio-quiet active galactic nucleus (AGN) at a high accretion rate of λ _Edd = 0.19 ± 0.04. This particular AGN hosts an ionized gas outflow with the largest spatial offset from its nucleus compared ...

SEARCH FOR A COMPACT SCINTILLATING COMPONENT IN SNR 3С58 AT DECAMETER WAVELENGTHS

Radio Physics and Radio Astronomy, 2014
The upper limit for the flux of a compact source of continuum radio emission in SNR 3C58, (2.7 ± 0.9) Jy, was obtained by the highest sensitive observations of interplanetary scintillations at decameter wavelengths.

VLT spectropolarimetry of two powerful radio galaxies at z~1.4: UV continuum, emission-line properties and the nature of high-redshift dust

, 2004
(Abridged) Deep VLT spectropolarimetric observations are presented for two powerful radio galaxies, 0850-206 and 1303+091. These observations cover the rest-frame wavelength range ~ 1450 - 3750 A.

Tracking the Enigmatic Globular Cluster Ultracompact X-Ray Binary X1850–087: Extreme Radio Variability in the Hard State

The Astrophysical Journal, 2023
The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850–087, located in the globular cluster NGC 6712, is a persistent atoll-type X-ray source that has

The Detection and Characterization of Centimeter Radio Continuum Emission from the Low-Mass Protostar L1014-IRS [PDF]

, 2007
Observations by the Cores to Disk Legacy Team with the Spitzer Space Telescope have identified a low-luminosity, mid-infrared source within the dense core, Lynds 1014, which was previously thought to harbor no internal source. Follow-up near-infrared and

Sub-arcsecond imaging of the radio continuum and neutral hydrogen in the Medusa merger

, 2005
We present sub-arcsecond, Multi-Element Radio Linked Interferometer (MERLIN) observations of the decimetre radio continuum structure and neutral hydrogen (HI) absorption from the nuclear region of the starburst galaxy NGC 4194 (the Medusa Merger).
