Projection-Enhanced Disk Breaks: Evidence from Deep Photometric Decomposition
Sergey S. Savchenko, Ilia V. Chugunov, Alexander A. Marchuk +5
Radial brightness profiles of disk galaxies often exhibit so-called breaks -- locations where their exponential-scale length abruptly changes. Some galaxies have downbending (Type…
The Edge-on Galaxies in the DESI survey (EGIDE): sample building and photometry
Alexander A. Marchuk, Sergey S. Savchenko, Dmitry I. Makarov +7
We present the EGIDE (The Edge-on Galaxies in the DESI survey) project - a catalogue of 149,215 edge-on galaxy candidates created using the data of the DESI Legacy Imaging Survey D…
A New Cartwheel-like Collisional Ring Galaxy
Vladimir P. Reshetnikov, Sergey S. Savchenko, Alexander A. Marchuk +5
We report the discovery of a new Cartwheel-type collisional ring galaxy, PGC\,1112751, which we named ``Eridanus Wheel'' (EW). Such systems result from head-on collisions between g…
Tango of Titans: Centaurus A and M83 as a Local Group Analog
David Benisty, Noam Libeskind, Dmitry Makarov
Centaurus A (CenA) and M83 form one of the most massive galaxy pairs in the nearby Universe. Although their observed heliocentric velocities suggest motion that is not obviously in…
Tracing satellite planes in the Sculptor group: II. Discovery of five faint dwarf galaxies in the DESI Legacy Survey
David Martinez-Delgado, Michael Stein, Marcel S. Pawlowski +5
Although substantial progress has been made in reconciling LCDM simulations with the observed abundance and distribution of satellite galaxies, important tensions persist. Studying…
Edge-on galaxies relative to edge-on view of the Local Supercluster
P. Dolgosheeva, D. Makarov, N. Libeskind
Cosmological theories suggest that the angular momentum of galaxies should be closely linked to the structure of the cosmic web. The Local Supercluster is the closest and most stud…
