Too many quiescent late-type galaxies or a matter of misclassification?

J. L. Tous, S. I. Raimundo, H. Domínguez Sánchez

In the local Universe, the terms late-type and early-type are used to describe, respectively, disc galaxies with spiral arms and more bulge-dominated systems lacking spiral structu…

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…

Kinematic misalignment as a driver of black hole activity in galaxies with external interactions

Sandra I. Raimundo, Rogerio Riffel, Song-lin Li +6

The process of Active Galactic Nuclei (AGN) fuelling relies on the transport of gas across several orders of magnitude in physical scale until the gas reaches the supermassive blac…

The distribution of lenticular galaxies in the phase space of present-day galaxy cluster regions

M. Gort, J. L. Tous, J. M. Solanes

We investigate the environmental impact of cluster regions on the evolution of nearby S0 galaxies, focusing on their distinct quiescent and star-forming (SF) subpopulations. We sel…

Fully comprehensive diagnostic of galaxy activity using principal components of visible spectra: implementation on nearby S0s

J. L. Tous, J. M. Solanes, J. D. Perea

We introduce a novel galaxy classification methodology based on the visible spectra of a sample of over 68,000 nearby () Sloan Digital Sky Survey lenticular (S0) galaxie…
