Strength Ratios of Diffuse Interstellar Bands in Slightly Reddened Objects
UniverseThe disk of the Milky Way fills the interstellar medium in the form of discrete clouds, many (∼30) light-years across. The average density of this medium is 1 hydrogen atom per cm3 (Oort limit), in the clouds—several dozen atoms, and between the clouds ...

Modeling the Optical Colors of Galactic Cirrus Clouds in the Stripe 82 Region
The Astronomical JournalObservations have shown that the optical colors of Galactic cirrus clouds differ significantly from those of extragalactic sources; thus, they can be used to distinguish Galactic cirrus from extragalactic low surface brightness (LSB) features.

Mapping Galactic Dust Emission and Extinction with H I, H II, and H2
The Astrophysical JournalNeutral hydrogen (H i ) emission closely traces the dust column density at high Galactic latitudes and is thus a powerful tool for predicting dust extinction. However, the relation between H i column density N _HI and high-latitude dust emission observed

Complex K: Supernova Origin of Anomalous-velocity H i Structure
The Astrophysical JournalWe address one of the lingering mysteries of high-velocity clouds: If the anomalous negative velocities are the result of the approaching gas from old supernovae, then where are the receding counterparts of the expanding shells?

On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds
The Astrophysical Journal, 2023 We look into the 2851 ^12 CO molecular clouds harboring ^13 CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal ^13 CO structures.

Tracing the Layers of Photodissociated Gas in the Trifid Nebula
The Astrophysical JournalPhotodissociated gas bears the signature of the dynamical evolution of the ambient interstellar medium impacted by the mechanical and radiative feedback from an expanding H ii region.

What Rogue Hydrogen Clouds Tell Us about Galactic Magnetic Fields
The Astrophysical JournalObservations of the Milky Way and external galaxies support the idea that large-scale magnetic fields are concentrated in galactic disks, with halo magnetic fields at least an order of magnitude weaker.

DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES
Odessa Astronomical Publications, 2008 We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.

INVESTIGATION OF DIFFUSE INTERSTELLAR BANDS OF ORGANIC MOLECULES IN THE SPECTRA OF CEPHEID STARS
Odessa Astronomical Publications, 2016 We describe an effective method of investigation of the Diffuse Interstellar Bands (DIBs) in the spectra of Cepheid stars. DIBs are believed to originate from the absorption of such carriers as polycyclic aromatic hydrocarbons in the interstellar gaseous
