DISCOVERY OF A PSEUDOBULGE GALAXY LAUNCHING POWERFUL RELATIVISTIC JETS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT Supermassive black holes launching plasma jets at close to the speed of light, producing gamma-rays, have ubiquitously been found to be hosted by massive elliptical galaxies. Since elliptical galaxies are generally believed to be built through galaxy mergers, active galactic nuclei (AGN) launching relativistic jets are ...

Jets, bubbles, and heat pumps in galaxy clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
Abstract Feedback from active galactic nucleus (AGN) jets has been proposed to counteract the catastrophic cooling in many galaxy clusters. However, it is still unclear which physical processes are acting to couple the energy from the bi-directional jets to the intra-cluster medium (ICM).

Origin of very high energy emission in galaxy clusters

open access: yesEPJ Web of Conferences, 2017
The Perseus cluster of galaxies with the central galaxy NGC 1275 is ideally suitable for studying both the physics of relativistic jets from Active Galactic Nuclei and for revealing the feedback role of the central galaxy.

The Multiwavelength Environment of Second Bologna Catalog Sources

open access: yesThe Astrophysical Journal Supplement Series, 2023
We present the first results of the Chandra Cool Targets (CCT) survey of the Second Bologna Catalog (B2CAT) of powerful radio sources, aimed at investigating the extended X-ray emission surrounding these sources.

CCD observations of galaxies with radio jets [PDF]

open access: yesSymposium - International Astronomical Union, 1986
We present preliminary results of a CCD survey of nearby (z<0.1) northern galaxies which have well defined radio jets. Our main objectives are to: 1) detect - or put constraints to - the presence of optical jets in these galaxies, 2) obtain high dynamic range maps of known optical jets, and 3) make a detailed comparison of our results with those ...

Jetted narrow-line Seyfert 1 galaxies breaking the jet paradigm: A comprehensive study of host-galaxy morphologies

open access: yesAstronomy & Astrophysics, 2022
Narrow-line Seyfert 1 (NLS1) galaxies are unevolved active galactic nuclei (AGNs) that exist predominantly in spiral galaxies. However, mostly due to the small number of sources studied, it has been under debate whether also the hosts of jetted NLS1 galaxies, a particular subclass of these sources hosting a relativistic jet, are disk-like or elliptical,

Superdiscs in radio galaxies: jet–wind interactions [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2007
Taking a clue from their sharp-edged (strip-like) morphology observed in several cases, a new mechanism is proposed for the formation of the emission gaps seen between the radio lobes of many powerful extragalactic double radio sources. Canonical understanding of the radio gaps invokes either blocking of the back-flowing lobe plasma by the denser ...

Efficient Long-range Active Galactic Nuclei (AGNs) Feedback Affects the Low-redshift Lyα Forest

open access: yesThe Astrophysical Journal Letters, 2023
Active galactic nuclei (AGNs) feedback models are generally calibrated to reproduce galaxy observables such as the stellar mass function and the bimodality in galaxy colors.
