Regularly Spaced Infrared Peaks in the Dusty Spirals of Messier 100
Bruce G. Elmegreen, Debra Meloy Elmegreen, Yuri N. Efremov
Spitzer Space Telescope InfraRed Array Camera (IRAC) images of M100 show numerous long filaments with regularly-spaced clumps, suggesting the associated cloud complexes formed by l…
Imaging and spectroscopic observations of a strange elliptical bubble in the northern arm of the spiral galaxy NGC 6946
Yuri N. Efremov, Alexei V. Moiseev
NGC 6946, known as the Fireworks galaxy because of its high supernova rate and high star formation, is embedded in a very extended HI halo. Its northern spiral arm is well detached…
A spectral and photometric study of 102 star forming regions in seven spiral galaxies
A. S. Gusev, F. Sakhibov, A. E. Piskunov +7
We present a study of complexes of young massive star clusters (YMCs), embedded in extragalactic giant HII regions, based on the coupling of spectroscopic with photometric and spec…
Embedded Star Formation in S4G Galaxy Dust Lanes
Debra M. Elmegreen, Bruce G. Elmegreen, Santiago Erroz-Ferrer +22
Star-forming regions that are visible at 3.6 microns and Halpha but not in the u,g,r,i,z bands of the Sloan Digital Sky survey (SDSS), are measured in five nearby spiral galaxies t…
Regular chains of star formation complexes in spiral arms of NGC 628
Alexander S. Gusev, Yuri N. Efremov
We investigate photometric properties of spiral arms and stellar complexes/associations inside these arms in the grand design NGC 628 (M74) galaxy.We analyze GALEX ultraviolet, opt…
Giant stellar arcs in the Large Magellanic Cloud: a possible link with past activity of the Milky Way nucleus
Yuri N. Efremov
The origin of the giant stellar arcs in the LMC remains a controversial issue, discussed since 1966. No other stellar arc is so perfect a segment of a circle, moreover, there is an…
