NEAR-IR Spectroscopy of Young Stars in the Braid Nebula Star Formation Region in Cygnus Ob7
Colin Aspin, Tracy L. Beck, Tae-Soo Pyo +8
We present 1.4 to 2.5 um integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data forms one aspect of a large-scale multi-wavelen…
Early-type galaxies with core collapse supernovae
A. A. Hakobyan, A. R. Petrosian, B. McLean +4
It is widely accepted that the progenitors of core collapse SNe are young massive stars and therefore their host galaxies are mostly spiral or irregular galaxies dominated by a you…
Flattening of Galaxies of Different Morphological Types in Subclusters of Coma
N. G. Kogoshvili, T. M. Borchkhadze, A. T. Kalloghlian
The dependence of flattening of galaxies on the density of galaxies in subclusters selected around galaxies NGC4889, NGC4874 and NGC4839 in the Coma cluster has been studied. The m…
Spitzer IRS Spectra of Optically Faint IRAS Sources
Lusine Sargsyan, Areg Mickaelian, Daniel Weedman +1
Extragalactic sources from the IRAS Faint Source Catalog (FSC) which have the optically faintest magnitudes (E > 18) were selected by spatial coincidence with a source in the FIRST…
The statistical investigation of type Ib/c and II supernovae and their host galaxies
A. A. Hakobyan
This is a statistical study of the properties of type Ib/c and II supernovae and of the integral parameters of their spiral host galaxies. The methods of one-dimensional and multiv…
Study of the HII regions in the spiral galaxy NGC6384
A. A. Hakobyan, A. R. Petrosian, A. A. Yeghiazaryan +1
The galaxy NGC6384 has been observed with an IPCS through H alpha and [NII] narrow-band interference filters for direct imagery with the 2.6 m Byurakan telescope. We studied main p…
