The Quasar Feedback Survey: Ionised Outflows in type 2 QSOs with MUSE data

M. Bianchin, C. M. Harrison, T. Costa +13

We study ionised gas properties in a sample of 18 luminous (log L erg/s) obscured QSOs at 0.085<z<0.2 observed with VLT/MUSE as part of the multi-wavelength Quasa…

Fuelling the central region of galaxies with misaligned gas accretion

J. L. Tous, S. I. Raimundo, R. Riffel +3

The paper investigates how gas that is kinematically misaligned with a galaxy’s disk fuels central star formation and potentially black‑hole growth, finding that this accretion sus…

Blowing star formation away in AGN hosts (BAH) -- V: The Feeding-Feedback Cycle in local AGNs as revealed by their stellar populations

Rogério Riffel, Rogemar A. Riffel, Gabriel L. Souza-Oliveira +9

We present a spatially resolved analysis of the stellar populations in the inner kiloparsec of NGC 3884, 3C 293, and CGCG 012-070. Using near-infrared spectroscopy, we reconstruct…

Blowing star formation away in AGN Hosts (BAH) -- IV: Feeding and feedback in 3C 293 observed with JWST NIRSpec

Maitê S. Z. de Mellos, Rogemar A. Riffel, Gabriel L. Souza-Oliveira +5

We use JWST/NIRSpec observations of the radio galaxy 3C 293 to map the emission, extinction, and kinematics of hot molecular and ionized gas, as well as stellar kinematics, within…

Investigating the clumpy star formation in an interacting dwarf irregular galaxy

Augusto E. Lassen, Ana L. Chies-Santos, Rogerio Riffel +9

Clumpy morphologies are more frequent in distant and low-mass star-forming galaxies. Therefore the less numerous nearby galaxies presenting kpc-sized clumps represent unique labora…

Blowing star formation away in AGN Hosts (BAH) -- II. Investigating the origin of the H2 emission excess in nearby galaxies with JWST MIRI

Rogemar A. Riffel, Gabriel L. Souza-Oliveira, José Henrique Costa-Souza +4

We use James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) medium-resolution spectrometer (MRS) observations of 3C 293 (UGC 8782), CGCG 012-070 and NGC 3884 to investi…
