We study photometric properties, chemical abundances and sizes of star formation regions in the two principal arms of the galaxy NGC 628 (M74). The GALEXultraviolet, optical U BVRI, and Hsurface photometry data are used, including those obtained with the 1.5-m telescope of the Maidanak Observatory. The thirty brightest star formation regions in ultraviolet light lo- cated in the spiral arms of NGC 628 are identified and studied. We find that the star formation regions in one (longer) arm are… 

A spectral and photometric study of 102 star forming regions in seven spiral galaxies

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 spectrophotometric

Peculiarities of the chemical abundance distribution in galaxies NGC 3963 and NGC 7292

Spectroscopic observations of 32 H ii regions in the spiral galaxy NGC 3963 and the barred irregular galaxy NGC 7292 were carried out with the 2.5-m telescope of the Caucasus Mountain Observatory of

Hierarchy and size distribution function of star formation regions in the spiral galaxy NGC 628

Hierarchical structures and size distribution of star form ation regions in the nearby spiral galaxy NGC 628 are studied over a range of scale from 50 to 1000 pc using optical images obtained with

Star formation rates and the kinematics of gas in the spiral arms of NGC 628

The relations between star formation rates along the spiral arms and the velocities of gas inflow into the arms in the grand-design galaxy NGC 628 were studied. We found that the radial distribution

We present an analysis of the metallicity and star formation activities of H II regions in the interacting system Arp 86, based on the first scientific observations using multi-object spectroscopy

The Tip of the Red Giant Branch Distance to the Perfect Spiral Galaxy M74 Hosting Three Core-Collapse Supernovae

M74 (NGC 628) is a famous face-on spiral galaxy, hosting three core-collapse supernovae (SNe):SN Ic 2002ap, SN II-P 2003gd, and SN II-P 2013ej. However its distance is not well known. We present a

Molecular and Atomic Gas in Star-forming Complexes: NGC 5194, NGC 5457, NGC 628, and NGC 6946

Abstract — We use observations of CO and HI emission in star-forming complexes (SFCs) in galaxies NGC 5457, NGC 5194, NGC 628, and NGC 6946 to search for possible correlations between atomic and


We utilize a suite of multiwavelength data of nine nearby spirals to analyze the shock-induced star formation sequence that may result from a constant spiral pattern speed. The sequence involves

Azimuthal propagation of star formation in nearby spiral galaxies: NGC 628, NGC 3726, and NGC 6946

Star formation induced by a spiral shock wave, which in turn is generated by a spiral density wave, produces an azimuthal age gradient across the spiral arm, which has opposite signs on either side

Missing stellar mass in SED fitting: spatially unresolved photometry can underestimate galaxy masses

We fit model spectral energy distributions to each pixel in 67 nearby ( =0.0057) galaxies using broadband photometry from the Sloan Digital Sky Survey and GALEX. For each galaxy, we compare the



Regular chains of star formation complexes in spiral arms of NGC 628

We investigate photometric properties of spiral arms and stellar complexes/associations inside these arms in the grand design NGC 628 (M 74) galaxy. We analyze GALEXultraviolet, opti- cal U BVRI, and
