A Hero's Little Horse: Discovery of a Dissolving Star Cluster in Pegasus
Dongwon Kim, Helmut Jerjen
We report the discovery of an ultra-faint stellar system in the constellation of Pegasus. This concentration of stars was detected by applying our overdensity detection algorithm t…
The Extended Virgo Cluster Catalog
Suk Kim, Soo-Chang Rey, Helmut Jerjen +7
We present a new catalog of galaxies in the wider region of the Virgo cluster, based on the Sloan Digital Sky Survey (SDSS) Data Release 7. The Extended Virgo Cluster Catalog (EVCC…
The properties of early-type galaxies in the Ursa Major cluster
Mina Pak, Soo-Chang Rey, Thorsten Lisker +5
Using SDSS-DR7 and NASA/IPAC Extragalactic Database spectroscopic data, we identify 166 galaxies as members of the Ursa Major cluster with Mr < -13.5 mag. We morphological classify…
Deep Near-Infrared Surface Photometry and Properties of Local Volume Dwarf Irregular Galaxies
T. Young, H. Jerjen, Á. R. López-Sánchez +1
We present deep H-band surface photometry and analysis of 40 Local Volume galaxies, a sample primarily composed of dwarf irregulars in the Cen A group, obtained using the IRIS2 det…
Co-orbiting satellite galaxy structures are still in conflict with the distribution of primordial dwarf galaxies
Marcel S. Pawlowski, Benoit Famaey, Helmut Jerjen +11
Both major galaxies in the Local Group host planar distributions of co-orbiting satellite galaxies, the Vast Polar Structure (VPOS) of the Milky Way and the Great Plane of Andromed…
Metal-poor dwarf galaxies in the SIGRID galaxy sample. II. The electron temperature-abundance calibration and the parameters that affect it
David C. Nicholls, Michael A. Dopita, Ralph S. Sutherland +3
In this paper, we use the Mappings photoionization code to explore the physical parameters that impact on the measurement of electron temperature and abundance in HII regions. In t…
