MUSE-ALMA Haloes X: The stellar masses of gas-rich absorbing galaxies
Ramona Augustin, Céline Péroux, Arjun Karki +13
The physical processes by which gas is accreted onto galaxies, transformed into stars and then expelled from galaxies are of paramount importance to galaxy evolution studies. Obser…
MUSE-ALMA Haloes IX: Morphologies and Stellar Properties of Gas-rich Galaxies
Arjun Karki, Varsha P. Kulkarni, Simon Weng +15

Mapping Accreted Stars in Early-Type Galaxies Across the Mass-Size Plane
Thomas A. Davison, Mark A. Norris, Ryan Leaman +3
Galaxy mergers are instrumental in dictating the final mass, structure, stellar populations, and kinematics of galaxies. Cosmological galaxy simulations indicate that the most mass…
Old and New Major Mergers in the SOSIMPLE galaxy, NGC 7135
Thomas A. Davison, Harald Kuntschner, Bernd Husemann +7
The simultaneous advancement of high resolution integral field unit spectroscopy and robust full-spectral fitting codes now make it possible to examine spatially-resolved kinematic…
Asymmetric spatial distribution of sub-solar metallicity stars in the Milky Way nuclear star cluster
A. Feldmeier-Krause, W. Kerzendorf, T. Do +10
We present stellar metallicity measurements of more than 600 late-type stars in the central 10 pc of the Galactic centre. Together with our previously published KMOS data, this dat…
Formation channels of slowly rotating early-type galaxies
Davor Krajnović, Ugur Ural, Harald Kuntschner +11
We study the evidence for a diversity of formation processes in early-type galaxies by presenting the first complete volume-limited sample of slow rotators with both integral-field…
A Two-Dimensional Spectroscopic Study of Emission Line Galaxies in the Faint Infrared Grism Survey (FIGS) I: Detection Method and Catalog
Norbert Pirzkal, Barry Rothberg, Russell E. Ryan +31
We present the results from the application of a two-dimensional emission line detection method, EMission-line two-Dimensional (EM2D), to the near-infrared G102 grism observations…
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

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 hELENa project - II. Abundance distribution trends of early-type galaxies: from dwarfs to giants
Agnieszka Sybilska, Harald Kuntschner, Glenn van de Ven +4

A Deconvolution Technique to Correct Deep Images of Galaxies from Instrumental Scattered Light
Emin Karabal, Pierre-Alain Duc, Harald Kuntschner +3
Deep imaging of the diffuse light emitted by the stellar fine structures and outer halos around galaxies is now often used to probe their past mass assembly. Because the extended h…
Spatially resolved star formation relation in two HI-rich galaxies with central post-starburst signature
