Host galaxies of jetted narrow-line Seyfert 1 galaxies [PDF]
Proceedings of Revisiting narrow-line Seyfert 1 galaxies and their place in the Universe — PoS(NLS1-2018), 2018 Host galaxy morphology studies of jetted narrow-line Seyfert 1 galaxies (NLS1) are scarce; so far only three of them have been investigated in detail. Though all three are hosted by late-type galaxies the sample size is too small to establish a preferred host galaxy type for jetted NLS1 sources; increasing the sample size is crucial to achieve ...

Relativistic Jets in Gamma-Ray-Emitting Narrow-Line Seyfert 1 Galaxies [PDF]
, 2019 Before the launch of the Fermi Gamma-ray Space Telescope satellite only two classes of active galactic nuclei (AGN) were known to generate relativistic jets and thus to emit up to the γ -ray energy range: blazars and radio galaxies, both hosted in giant ...

A radio-jet-galaxy interaction in 3C 441 [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 Multi-wavelength imaging and spectroscopy of the z=0.708 radio galaxy 3C441 and a red aligned optical/infrared component are used to show that the most striking aspect of the radio-optical ``alignment effect'' in this object is due to the interaction of the radio jet with a companion galaxy in the same group or cluster.

Sources of Relativistic Jets in the Galaxy [PDF]
Annual Review of Astronomy and Astrophysics, 1999 ▪ Abstract Black holes of stellar mass and neutron stars in binary systems are first detected as hard X-ray sources using high-energy space telescopes. Relativistic jets in some of these compact sources are found by means of multiwavelength observations with ground-based telescopes.

A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies [PDF]
, 2016 The discovery by the Large Area Telescope on board Fermi of variable γ-ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies revealed the presence of a possible third class of Active Galactic Nuclei (AGN) with relativistic jets in addition ...

Jittering jets by negative angular momentum feedback in cooling flows
, 2022 I apply the jittering jets in cooling flow scenario to explain the perpendicular to each other and almost coeval two pairs of bubbles in the cooling flow galaxy cluster RBS 797, and conclude that the interaction of the jets with the cold dense clumps ...

The Jet-Cloud Interaction in 3CR Galaxies: Preliminary Results in Four Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe present preliminary results of the Gemini/GMOS longslit spectra for four radiogalaxies: 3C 135, 3C 180, 3C 234 and 3C 284. These objects are a subsample of a set of galaxies with noticeable extended structure selected from the HST/WFPC2 3CR Snapshot Survey, data taken with the filters F555W, F702W and narrow-ramp.

POWERFUL RELATIVISTIC JETS IN SPIRAL GALAXIES [PDF]
International Journal of Modern Physics: Conference Series, 2012 The discovery of high-energy (E > 100 MeV) γ rays from Narrow-Line Seyfert 1 Galaxies (γ-NLS1s) has confirmed the presence of powerful relativistic jets in this class of active galactic nuclei (AGN). Although the jet emission is similar to that of blazars and radio galaxies, γ-NLS1s have some striking differences: relatively small masses (106-8 M⊙),
