Ultra-Diffuse Galaxies A Distinct Population? Dwarf Galaxies in the Coma Cluster and A262 from Deep Wendelstein Imaging Data
Raphael Zöller, Matthias Kluge, Benjamin Staiger +1
In this study, we compare the structural parameters of ultra-diffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population. We ob…
Central radio galaxies in galaxy clusters: Joint surveys by eROSITA and ASKAP
K. Böckmann, M. Brüggen, B. Koribalski +18
The extended ROentgen Survey with an Imaging Telescope Array (eROSITA) telescope onboard the Spectrum-Roentgen-Gamma (SRG) mission has finished the first eROSITA All-Sky Survey (eR…
Composite Bulges -- III. A Study of Nuclear Star Clusters in Nearby Spiral Galaxies
Aishwarya Ashok, Anil Seth, Peter Erwin +17
We present photometric and morphological analyses of nuclear star clusters (NSCs) -- very dense, massive star clusters present in the central regions of most galaxies -- in a sampl…
The eROSITA Final Equatorial-Depth Survey (eFEDS): A Machine Learning Approach to Infer Galaxy Cluster Masses from eROSITA X-ray Images
Sven Krippendorf, Nicolas Baron Perez, Esra Bulbul +15
We develop a neural network based pipeline to estimate masses of galaxy clusters with a known redshift directly from photon information in X-rays. Our neural networks are trained u…
Minor Mergers are not enough: The importance of Major Mergers during Brightest Cluster Galaxy assembly
Matthias Kluge, Ralf Bender
We investigate the roles of major and minor mergers during brightest cluster galaxy (BCG) assembly using surface brightness profiles, line indices, and fundamental plane relations.…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
A Trail of the Invisible: Blue Globular Clusters Trace the Radial Density Distribution of the Dark Matter -- Case Study of NGC 4278
Matthias Kluge, Rhea-Silvia Remus, Iurii V. Babyk +2
We present new, deep optical observations of the early-type galaxy NGC 4278, which is located in a small loose group. We find that the galaxy lacks fine substructure, i.e., it appe…
