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…
SILVERRUSH. V. Census of Lya, [OIII]5007, Ha, and [CII]158um Line Emission with ~1000 LAEs at z=4.9-7.0 Revealed with Subaru/HSC
Yuichi Harikane, Masami Ouchi, Takatoshi Shibuya +23
We investigate Lya, [OIII]5007, Ha, and [CII]158um emission from 1124 galaxies at z=4.9-7.0. Our sample is composed of 1092 Lya emitters (LAEs) at z=4.9, 5.7, 6.6, and 7.0 identifi…
Atmospheric stellar parameters for large surveys using FASMA, a new spectral synthesis package
M. Tsantaki, D. T. Andreasen, G. D. C. Teixeira +4
In the era of vast spectroscopic surveys focusing on Galactic stellar populations, astronomers want to exploit the large quantity and good quality of data to derive their atmospher…
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…
The resolved star formation history of M51a through successive Bayesian marginalization
Eric E. Martínez-García, Gustavo Bruzual, Gladis Magris C. +1
We have obtained the time and space-resolved star formation history (SFH) of M51a (NGC 5194) by fitting GALEX, SDSS, and near infrared pixel-by-pixel photometry to a comprehensive…
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…
