Spectro-Imaging Forward Model of Red and Blue Galaxies
Martina Fagioli, Luca Tortorelli, Jörg Herbel +3
For the next generation of spectroscopic galaxy surveys, it is important to forecast their performances and to accurately interpret their large data sets. For this purpose, it is n…
Measurement of the B-band Galaxy Luminosity Function with Approximate Bayesian Computation
Luca Tortorelli, Martina Fagioli, Jörg Herbel +3
The galaxy Luminosity Function (LF) is a key observable for galaxy formation, evolution studies and for cosmology. In this work, we propose a novel technique to forward model wide-…
The MUSE Atlas of Disks (MAD): Ionized gas kinematic maps and an application to Diffuse Ionized Gas
Mark den Brok, C. Marcella Carollo, Santiago Erroz-Ferrer +9
We have obtained data for 41 star forming galaxies in the MUSE Atlas of Disks (MAD) survey with VLT/MUSE. These data allow us, at high resolution of a few 100 pc, to extract ionize…
Forward Modeling of Spectroscopic Galaxy Surveys: Application to SDSS
Martina Fagioli, Julian Riebartsch, Andrina Nicola +6
Galaxy spectra are essential to probe the spatial distribution of galaxies in our Universe. To better interpret current and future spectroscopic galaxy redshift surveys, it is impo…
Minor Mergers or Progenitor Bias? The Stellar Ages of Small and Large Quenched Early-Type Galaxies
Martina Fagioli, C. Marcella Carollo, Alvio Renzini +3
We investigate the origin of the evolution of the population-averaged size of quenched galaxies (QGs) through a spectroscopic analysis of their stellar ages. The two most favoured…
NGC 3628-UCD1: A possible Cen Analog Embedded in a Stellar Stream
Zachary G. Jennings, Aaron J. Romanowsky, Jean P. Brodie +6
Using Subaru/Suprime-Cam wide-field imaging and both Keck/ESI and LBT/MODS spectroscopy, we identify and characterize a compact star cluster, which we term NGC 3628-UCD1, embedded…
How elevated is the dynamical-to-stellar mass ratio of the ultra-compact dwarf S999?
Joachim Janz, Duncan A. Forbes, Mark A. Norris +4
Here we present new Keck ESI high-resolution spectroscopy and deep archival HST/ACS imaging for S999, an ultra-compact dwarf in the vicinity of M87, which was claimed to have an ex…
