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 ...

The Astrophysical Journal, 2023 Powerful radio sources associated with supermassive black holes are among the most luminous objects in the universe, and are frequently recognized both as cosmological probes and active constituents in the evolution of galaxies.

WATCAT: a tale of wide-angle tailed radio galaxies
, 2019 We present a catalog of 47 wide-angle tailed radio galaxies (WATs), the WATCAT; these galaxies were selected by combining observations from the National Radio Astronomy Observatory/Very Large Array Sky Survey (NVSS), the Faint Images of the Radio Sky at ...

Quantifying angular clustering in wide-area radio surveys [PDF]
, 2002 We quantify the angular clustering of radio galaxies in the NVSS and FIRST radio surveys using the two-point correlation function and the moments of counts-in-cells - both important points of comparison with theory.

International Journal of Cancer, EarlyView.Basal‐like breast cancer (BLBC) is aggressive and often exhibits inherent or acquired resistance to radiotherapy (RT), a primary treatment option. RT resistance is underpinned by molecular alterations, many of which are poorly understood. Here, RT‐induced transcriptomic changes were analyzed using bulk and spatial sequencing in a BLBC mouse model and ...

, 2003 Recent results on the radio emission from galaxy clusters are reviewed, with emphasis both on the radio galaxies and on the diffuse radio emission from the intracluster medium. We show that the formation of the tailed morphology in cluster radio galaxies is due to the effect of the cluster gaseous environment and of its large scale motions in merging ...

The fundamental plane of radio galaxies [PDF]
Astronomy & Astrophysics, 2001 We collected photometrical and dynamical data for 73 low red-shift (z<0.2) Radio Galaxies (LzRG) in order to study their Fundamental Plane (FP). For 22 sources we also present new velocity dispersion data, that complement the photometric data given in our previous study of LzRG (Govoni et al. 2000a). It is found that the FP of LzRG is similar to the

The Astrophysical JournalWe present a detailed study of radio-detected dwarf galaxies ( M _⋆ ≲ 3 × 10 ^9 M _⊙ ) to characterize extreme star formation and search for (variable) radio active galactic nuclei (AGNs). Our sample comes from A. E.

Pair-Matching of Radio-Loud and Radio-Quiet AGNs
Frontiers in Astronomy and Space Sciences, 2017 Active galactic nuclei (AGNs) are known to cover an extremely broad range of radio luminosities and the spread of their radio-loudness is very large at any value of the Eddington ratio.

The dust masses of powerful radio galaxies: clues to the triggering of their activity [PDF]
, 2014 We use deep Herschel Space Observatory observations of a 90% complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 < z < 0.7) to estimate the dust masses of their host galaxies and thereby investigate the triggering mechanisms for their ...
