Glimmering in the dark: modeling the low-mass end of the relation and of the quasar luminosity function
Fabio Pacucci, Abraham Loeb, Mar Mezcua +1
The relation establishes a connection between central black holes (BHs) and their host spheroids. Supported by observations at $M_{\bullet} \gtrsim 10^5 \, M_{\od…
Spectroscopic characterisation of the stellar content of ultra diffuse galaxies
T. Ruiz-Lara, M. A. Beasley, J. Falcón-Barroso +7
Understanding the peculiar properties of Ultra Diffuse Galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and exquisite data reductio…
Exploring the limits of AGN feedback: black holes and the star formation histories of low-mass galaxies
Ignacio Martin-Navarro, Mar Mezcua
Energy feedback, either from active galactic nuclei (AGN) or from supernovae, is required to understand galaxy formation within a -Cold Dark Matter cosmology. We study a sample…
Origins of ultra-diffuse galaxies in the Coma cluster - I. Constraints from velocity phase-space
Adebusola Alabi, Anna Ferré-Mateu, Aaron J. Romanowsky +8
We use Keck/DEIMOS spectroscopy to confirm the cluster membership of 16 ultra-diffuse galaxies (UDGs) in the Coma cluster, bringing the total number of spectroscopically con- firme…
Timing the formation and assembly of early-type galaxies via spatially resolved stellar populations analysis
Ignacio Martin-Navarro, Alexandre Vazdekis, Jesus Falcon-Barroso +3
To investigate star formation and assembly processes of massive galaxies, we present here a spatially-resolved stellar populations analysis of a sample of 45 elliptical galaxies (E…
Black-hole-regulated star formation in massive galaxies
Ignacio Martin-Navarro, Jean P. Brodie, Aaron J. Romanowsky +2
Super-massive black holes, with masses larger than a million times that of the Sun, appear to inhabit the centers of all massive galaxies. Cosmologically-motivated theories of gala…
Origins of ultra-diffuse galaxies in the Coma cluster II. Constraints from their stellar populations
Anna Ferre-Mateu, Adebusola Alabi, Duncan A. Forbes +8
In this second paper of the series, we study with new Keck/DEIMOS spectra the stellar populations of seven spectroscopically confirmed ultra-diffuse galaxies (UDGs) in the Coma clu…
History and destiny of an emerging early-type galaxy: New IFU insights on the major-merger remnant NGC7252
John R. Weaver, Bernd Husemann, Harald Kuntschner +7
NGC7252, which is one of the nearest major-merger galaxy remnants, is an ideal laboratory to study the processes inherent to the transformation of disc galaxies to ellipticals as o…
