A prediction on the age of thick discs as a function of the stellar mass of the host galaxy
S. Comerón
One of the suggested thick disc formation mechanisms is that they were born quickly and in situ from a turbulent clumpy disc. Subsequently, thin discs formed slowly within them fro…
Examining supernova events in Type 1 active galactic nuclei
Beatriz Villarroel, Iñigo Imaz, Elisabeta Lusso +4
A statistical study of intermediate Palomar Transient Factory supernovae (SNe) in Type 1 AGN has shown a major deficit of supernovae around Type 1 AGN host galaxies, with respect t…
On the origins of up-bending breaks in disk galaxies
Aaron E. Watkins, Jarkko Laine, Sébastien Comerón +2
Using SPITZER 3.6m imaging, we investigate the physical and data-driven origins of up-bending (Type III) disk breaks. We apply a robust new break-finding algorithm to 175 low-in…
The Vanishing & Appearing Sources during a Century of Observations project: I. USNO objects missing in modern sky surveys and follow-up observations of a "missing star"
Beatriz Villarroel, Johan Soodla, Sébastien Comerón +19
In this paper we report the current status of a new research program. The primary goal of the "Vanishing & Appearing Sources during a Century of Observations" (VASCO) project is to…
On the varied origins of up-bending breaks in galaxy disks
Aaron E. Watkins, Jarkko Laine, Sébastien Comerón +2
Aims: Using a sample of 175 low-inclination galaxies from the SG, we investigate the origins of up-bending (Type III) breaks in the 3.6 m surface brightness profiles of di…
The kinematics of local thick discs do not support an accretion origin
Sébastien Comerón, Heikki Salo, Johan H. Knapen +1
Thick discs are nearly ubiquitous components of the discs of present-day galaxies. It has been proposed that a fraction of their stars has been accreted. Here, we aim to find wheth…
