The Abundance Properties of Nearby Late-Type Galaxies. \\ II. The Relation between Abundance Distributions and Surface Brightness Profiles
L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko +1
The relations between oxygen abundance and disk surface brightness (OH-SB relation) in the infrared W1 band are examined for a nearby late-type galaxies. The oxygen abundances were…
SMBH in Galactic Nuclei with Tidal Disruption of Stars
Shiyan Zhong, Peter Berczik, Rainer Spurzem
Tidal Disruption of stars by super massive central black holes from dense star clusters is modeled by high-accuracy direct -body simulation. The time evolution of the stellar ti…
Ultramassive Black Hole Coalescence
Fazeel Khan, Kelly Holley-Bockelmann, Peter Berczik
Although supermassive black holes (SMBHs) correlate well with their host galaxies, there is an emerging view that outliers exist. Henize 2-10, NGC 4889, and NGC1277 are examples of…
The Abundance Properties of Nearby Late-Type Galaxies.I. The Data
L. S. Pilyugin, E. K. Grebel, A. Y. Kniazev
We investigate the oxygen and nitrogen abundance distributions across the optical disks of 130 nearby late-type galaxies using around 3740 published spectra of HII regions. We use…
The Effects of Stellar Rotation. II. A Comprehensive Set of Starburst99 Models
Claus Leitherer, Sylvia Ekstrom, Georges Meynet +3
We present a new set of synthesis models for stellar populations obtained with Starburst99, which are based on new stellar evolutionary tracks with rotation. We discuss models with…
Star formation rates in nearby Markarian galaxies
V. E. Karachentseva, O. V. Melnyk, I. D. Karachentsev
The star formation rates for the 230 nearest Markarian galaxies with radial velocities V_LG<3500 km/s have been determined from their far ultraviolet fluxes obtained with the GALEX…
