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.

, 2009 We explore radio and spectroscopic properties of a sample of 14 miniature radio galaxies, i.e. early-type core galaxies hosting radio-loud AGN of extremely low radio power, 10^(27-29) erg s^(-1) Hz^(-1) at 1.4 GHz.

A Complete Sample of Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1982 We report here some preliminary results of a multi-wavelength study of a complete sample of radio galaxies. The sample is comprised of 93 radio sources from the Parkes 11 cm catalog which are identified with galaxies of 17th magnitude or brighter in the declination zone −17° to −40°. Our objective is to cross-correlate the radio, infrared, optical, and

Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity
Advanced Science, EarlyView.The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

Investigating the Star Formation Characteristics of Radio Active Galactic Nuclei
The Astrophysical JournalThe coevolution of supermassive black holes and their host galaxies represents a fundamental question in astrophysics. One approach to investigating this question involves comparing the star formation rates (SFRs) of active galactic nuclei (AGNs) with ...

Hunting Gamma-Ray-emitting FR0 Radio Galaxies in Wide-field Sky Surveys
The Astrophysical Journal, 2023 The latest entry in the jetted active galactic nuclei (AGN) family is the Fanaroff–Riley type 0 (FR0) radio galaxies. They share several observational characteristics, e.g., nuclear emission and host galaxy morphology, with FR I sources; however, they ...

The Clustering Of Galaxies Around Radio-Loud AGNs
, 2013 We examine the hypothesis that mergers and close encounters between galaxies can fuel AGNs by increasing the rate at which gas accretes towards the central black hole.

Starburst radio galaxies: general properties, evolutionary histories and triggering [PDF]
, 2010 In this paper we discuss the results of a programme of spectral synthesis modelling of a sample of starburst radio galaxies in the context of scenarios for the triggering of the activity and the evolution of the host galaxies.

THE TRIGGERING AND BIAS OF RADIO GALAXIES [PDF]
Multiwavelength AGN Surveys, 2004 We present new results on the clustering and three-dimensional distribution of radio galaxies from the Texas-Oxford NVSS Structure (TONS) survey. The TONS survey was constructed to look at the distribution of radio galaxies in a region of moderate (0 < z < 0.5) redshifts by matching NVSS sources with objects in APM catalogues to obtain a sample ...
