The Fifteenth Data Release of the Sloan Digital Sky Surveys: First Release of MaNGA Derived Quantities, Data Visualization Tools and Stellar Library
D. S. Aguado, Romina Ahumada, Andres Almeida +230
Twenty years have passed since first light for the Sloan Digital Sky Survey (SDSS). Here, we release data taken by the fourth phase of SDSS (SDSS-IV) across its first three years o…
The WAGGS project - II. The reliability of the calcium triplet as a metallicity indicator in integrated stellar light
Christopher Usher, Thomas Beckwith, Sabine Bellstedt +12
Using data from the WiFeS Atlas of Galactic Globular cluster Spectra we study the behaviour of the calcium triplet (CaT), a popular metallicity indicator in extragalactic stellar p…
Stellar populations and star formation histories of the nuclear star clusters in six nearby galaxies
Nikolay Kacharov, Nadine Neumayer, Anil C. Seth +4
The majority of spiral and elliptical galaxies in the Universe host very dense and compact stellar systems at their centres known as nuclear star clusters (NSCs). In this work we s…
A relation between characteristic stellar age of galaxies and their intrinsic shape
Jesse van de Sande, Nicholas Scott, Joss Bland-Hawthorn +15
Stellar population and stellar kinematic studies provide unique but complementary insights into how galaxies build-up their stellar mass and angular momentum. A galaxy's mean stell…
A quartet of black holes and a missing duo: probing the low-end of the Mbh - sigma relation with the adaptive optics assisted integral-field spectroscopy
Davor Krajnović, Michele Cappellari, Richard M. McDermid +8
We present mass estimates of supermassive black holes in six nearby fast rotating early-type galaxies (NGC4339, NGC4434, NGC4474, NGC4551, NGC4578 and NGC4762) with effective stell…
The Fornax3D project: overall goals, galaxy sample, MUSE data analysis and initial results
M. Sarzi, E. Iodice, L. Coccato +10
The Fornax cluster provides a uniquely compact laboratory to study the detailed history of early-type galaxies and the role played by environment in driving their evolution and the…
