Impact of asteroseismology on improving stellar ages determination
Yveline Lebreton
High precision photometry as performed by the CoRoT and Kepler satellites on-board instruments has allowed to detect stellar oscillations over the whole HR diagram. Oscillation fre…
MyGIsFOS: an automated code for parameter determination and detailed abundance analysis in cool stars
L. Sbordone, E. Caffau, P. Bonifacio +1
The current and planned high-resolution, high-multiplexity stellar spectroscopic surveys, as well as the swelling amount of under-utilized data present in public archives have led…
TAPAS, a web-based service of atmospheric transmission computation for astronomy
J. L. Bertaux, R. Lallement, S. Ferron +2
Spectra of astronomical targets acquired from ground-based instruments are affected by the atmospheric transmission. The authors and their institutes are developing a web-based ser…
Supermassive Black Holes and Their Host Galaxies - II. The correlation with near-infrared luminosity revisited
Ronald Läsker, Laura Ferrarese, Glenn van de Ven +1
We present an investigation of the scaling relations between Supermassive Black Hole (SMBH) masses (Mbh), and their host galaxies' K-band bulge (Lbul) and total (Ltot) luminosities…
The Next Generation Virgo Cluster Survey - Infrared (NGVS-IR): I. A new Near-UV/Optical/Near-IR Globular Cluster selection tool
Roberto P. Muñoz, Thomas H. Puzia, Ariane Lançon +35
The NGVS-IR project (Next Generation Virgo Survey - Infrared) is a contiguous near-infrared imaging survey of the Virgo cluster of galaxies. It complements the optical wide-field s…
JKCS041: a Coma cluster progenitor at z=1.803
S. Andreon, A. B. Newman, G. Trinchieri +3
Using deep two-color near-infrared HST imaging and unbiased grism spectroscopy we present a detailed study of the z=1.803 JKCS041 cluster. Uniquely, for a high redshift cluster, we…
