Ultra-diffuse galaxies in the Coma cluster: Probing their origin and AGN occupation fraction
Orsolya E. Kovacs, Akos Bogdan, Rebecca E. A. Canning
Ultra-diffuse galaxies (UDGs) exhibit low surface brightness, but their optical extent is comparable to Milky Way-type galaxies. Due to their peculiar properties, it remains ambigu…
Constraining the dark matter halo mass of isolated low-surface-brightness galaxies
Orsolya E. Kovacs, Akos Bogdan, Rebecca E. A. Canning
Recent advancements in the imaging of low-surface-brightness objects revealed numerous ultra-diffuse galaxies in the local Universe. These peculiar objects are unusually extended a…
Expanding the Sample: The Relationship Between the Black Hole Mass of BCGs and the Total Mass of Galaxy Clusters
Frederika Phipps, Akos Bogdan, Lorenzo Lovisari +3
Supermassive Black Holes (BHs) residing in brightest cluster galaxies (BCGs) are overly massive when considering the local relationships between the BH mass and stellar bulge mass…
The quest for stellar coronal mass ejections in late-type stars: I. Investigating Balmer-line asymmetries of single stars in Virtual Observatory data
Krisztián Vida, Martin Leitzinger, Levente Kriskovics +5
Flares and CMEs can have deleterious effects on their surroundings: they can erode atmospheres of orbiting planets over time and also have high importance in stellar evolution. Mos…
Detection of the Missing Baryons toward the Sightline of H1821+643
Orsolya E. Kovacs, Akos Bogdan, Randall K. Smith +2
Based on constraints from Big Bang nucleosynthesis and the cosmic microwave background, the baryon content of the high-redshift Universe can be precisely determined. However, at lo…
Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster
Akos Bogdan, Lorenzo Lovisari, Orsolya E. Kovacs +4
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large d…
