We present measurements of the near-infrared Ca II triplet (CaT, CaT*), Paschen (PaT), and magnesium (Mg I) indices for a well-studied sample of 19 bulges of...

PublicationThe Near-infrared Coronal Line Spectrum of 54 nearby Active Galactic Nuclei
The relationship between the emission of coronal lines (CLs) and nuclear activity in 36 Type 1 and 18 Type 2 active galactic nuclei (AGNs) is analyzed, for the...

PublicationThe Near-ultraviolet Continuum Radiation in the Impulsive Phase of HF/GF-type dMe Flares. I. Data
We present near-UV (NUV) flare spectra from the Hubble Space Telescope (HST)/Cosmic Origins Spectrograph during two moderate-amplitude U-band flares on the dM4e...

PublicationThe Nearest Ultra Diffuse Galaxy: UGC 2162
We describe the structural, stellar population and gas properties of the nearest ultra diffuse galaxy discovered so far: UGC 2162 (z = 0.00392 {R}e,g=1.7(+/- 0...

PublicationThe Number of Dwarf Satellites of Disk Galaxies versus their Bulge Mass in the Standard Model of Cosmology
There is a correlation between the bulge mass of the three main galaxies of the Local Group (LG), i.e., M31, Milky Way (MW), and M33, and the number of their...

PublicationThe Number of Tidal Dwarf Satellite Galaxies in Dependence of Bulge Index
We show that a significant correlation (up to 5σ) emerges between the bulge index, defined to be larger for a larger bulge/disk ratio, in spiral galaxies with...

PublicationThe Observed Evolution of the Stellar Mass-Halo Mass Relation for Brightest Central Galaxies
We quantify evolution in the cluster-scale stellar mass-halo mass (SMHM) relation's parameters using 2323 clusters and brightest central galaxies (BCGs) over...

PublicationThe Observed Mass Distribution of Galactic Black Hole LMXBs Is Biased against Massive Black Holes
The discovery of gravitational-wave radiation from merging black holes (BHs) also uncovered BHs with masses in the range of ≍20-160 M ⊙. In contrast, the most...

PublicationThe Odd Offset between the Galactic Disk and Its Bar in NGC~3906
We use mid-infrared 3.6 and 4.5 μm imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual...
