Census and classification of low-surface-brightness structures in nearby early-type galaxies from the MATLAS survey
Michal Bílek, Pierre-Alain Duc, Jean-Charles Cuillandre +9
The morphology of galaxies gives essential constraints on the models of galaxy evolution. The morphology of the features in the low-surface-brightness regions of galaxies has not b…
Parameter Estimation for Scarce Stellar Populations
V. H. Ramírez-Siordia, G. Bruzual, B. Cervantes Sodi +1
We present a Bayesian method to determine simultaneously the age, metallicity, distance modulus, and interstellar reddening by dust of any resolved stellar population, by comparing…
The integrated properties of the CALIFA galaxies: Model-derived galaxy parameters and quenching of star formation
T. Bitsakis, S. F. Sanchez, L. Ciesla +6
We present a study of the integrated properties of the 835 galaxies in the CALIFA survey. To derive the main physical parameters of the galaxies we have fitted their UV-to-IR spect…
Shocked POststarburst Galaxy Survey. III. The Ultraviolet Properties of SPOGs
Felipe Ardila, Katherine Alatalo, Lauranne Lanz +11
The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify galaxies in the transitional phase between actively star-forming and quiescence with nebular lines that are excited…
Modelling dust rings in early-type galaxies through a sequence of radiative transfer simulations and 2D image fitting
P. Bonfini, O. Gonzalez-Martin, J. Fritz +3
A large fraction of early-type galaxies (ETGs) host prominent dust features, and central dust rings are arguably the most interesting among them. We present here `Lord Of The Rings…
Herschel Spectroscopy of the Taffy Galaxies (UGC 12914/12915 = VV 254): Enhanced [C II] emission in the collisionally-formed bridge
B. W. Peterson, P. N. Appleton, T. Bitsakis +17
Using the PACS and SPIRE spectrometers on-board Herschel, we obtained observations of the Taffy galaxies (UGC 12914/12915) and bridge. The Taffy system is believed to be the result…
The distribution and ages of star clusters in the Small Magellanic Cloud: Constraints on the interaction history of the Magellanic Clouds
T. Bitsakis, R. A. Gonzalez-Lopezlira, P. Bonfini +5
We present a new study of the spatial distribution and ages of the star clusters in the Small Magellanic Cloud (SMC). To detect and estimate the ages of the star clusters we rely o…
Stellar Population Synthesis of star forming clumps in galaxy pairs and non-interacting spiral galaxies
Javier Zaragoza-Cardiel, Beverly J. Smith, Margarita Rosado +5
We have identified 1027 star forming complexes in a sample of 46 galaxies from the Spirals, Bridges, and Tails (SB&T) sample of interacting galaxies, and 693 star forming complexes…
Connecting traces of galaxy evolution: the missing core mass -- morphological fine structure relation
P. Bonfini, T. Bitsakis, A. Zezas +5
Deep exposure imaging of early-type galaxies (ETGs) are revealing the second-order complexity of these objects, which have been long considered uniform, dispersion-supported sphero…
A novel method to automatically detect and measure the ages of star clusters in nearby galaxies: Application to the Large Magellanic Cloud
T. Bitsakis, P. Bonfini, R. A. Gonzalez-Lopezlira +5
We present our new, fully-automated method to detect and measure the ages of star clusters in nearby galaxies, where individual stars can be resolved. The method relies purely on s…
Star formation driven galactic winds in UGC 10043
C. López-Cobá, S. F. Sánchez, A. V. Moiseev +15
We study the galactic wind in the edge-on spiral galaxy UGC 10043 with the combination of the CALIFA integral field spectroscopy data, scanning Fabry-Perot interferometry (FPI), an…
Welcome to the Twilight Zone: The Mid-Infrared Properties of Poststarburst Galaxies
K. Alatalo, T. Bitsakis, L. Lanz +17
We investigate the optical and Wide-field Survey Explorer (WISE) colors of "E+A" identified post-starburst galaxies, including a deep analysis on 190 post-starbursts detected in th…
After the interaction: an efficiently star-forming molecular disk in NGC5195
Katherine Alatalo, Rebeca Aladro, Kristina Nyland +4
We present new molecular gas maps of NGC5195 (alternatively known as M51b) from the Combined Array for Research in Millimeter Astronomy (CARMA), including 12CO(1-0), 13CO(1-0), CN(…
Studying the evolution of galaxies in compact groups over the past 3 Gyr - II. The importance of environment in the suppression of star formation
