Two types of distribution of the gas velocity dispersion of MaNGA galaxies

L. S. Pilyugin, I. A. Zinchenko, M. A. Lara-Lopez +2

The distribution of the gas velocity dispersion sigma across the images of 1146 MaNGA galaxies is analyzed. We find that there are two types of distribution of the gas velocity dis…

The impact of physiological stress conditions on protein structure and trypsin inhibition of serine protease inhibitor Kazal type 1 (SPINK1) and its N34S variant

Ina Buchholz, Felix Nagel, Annelie Klein +6

One of the most common mutations in the serine protease inhibitor Kazal type 1 (SPINK1) gene is the N34S variant which is strongly associated with chronic pancreatitis. Although it…

Classification by Attention: Scene Graph Classification with Prior Knowledge

Sahand Sharifzadeh, Sina Moayed Baharlou, Volker Tresp

A major challenge in scene graph classification is that the appearance of objects and relations can be significantly different from one image to another. Previous works have addres…

Nuclear clocks for testing fundamental physics

E. Peik, T. Schumm, M. S. Safronova +3

The low-energy, long-lived isomer in Th, first studied in the 1970s as an exotic feature in nuclear physics, continues to inspire a multidisciplinary community of physicist…

The Black Hole Entropy Distance Conjecture and Black Hole Evaporation

Marvin Lüben, Dieter Lust, Ariadna Ribes Metidieri

We extend the recently proposed Black Hole Entropy Distance Conjecture to the case of charged black holes in de Sitter space. By systematically studying distances in the space of b…

The Abell 3391/95 galaxy cluster system: A 15 Mpc intergalactic medium emission filament, a warm gas bridge, infalling matter clumps, and (re-) accelerated plasma discovered by combining SRG/eROSITA data with ASKAP/EMU and DECam data

T. H. Reiprich, A. Veronica, F. Pacaud +44

We used dedicated SRG/eROSITA X-ray, ASKAP/EMU radio, and DECam optical observations of a 15 sq.deg region around the interacting galaxy cluster system A3391/95 to study the warm-h…
