oMEGACat. VII. Tracing Interstellar and Intracluster Medium of ω Centauri Using Sodium Absorptions
The Astrophysical JournalWe investigate the foreground interstellar medium along the line of sight and intracluster medium of ω Centauri ( ω Cen) by measuring the equivalent width of Na I D absorptions from MUSE observations. The large line-of-sight velocity difference between ω

Star formation across cosmic time
Fundamental Plasma PhysicsThe interstellar medium of galaxies is composed of multiple phases, including molecular, atomic, and ionized gas, as well as dust. Stars are formed within this medium from cold molecular gas clouds, which collapse due to their gravitational attraction ...

The Astrophysical Journal, 2023 Interstellar turbulence shapes the H i distribution in the Milky Way (MW). How this affects large-scale statistical properties of H i column density across the MW remains largely unconstrained.

Dust and gas in star-forming complexes in NGC 3351, NGC 5055, and NGC 5457
Open Astronomy, 2023 We present a study of the interstellar medium parameters in star-forming complexes (SFCs) in NGC 3351, NGC 5055, and NGC 5457 galaxies. This study concludes our previous investigations of gas and dust in a number of spiral galaxies.

H i Kinematics and the E(B − V)/N(H i) Ratio
The Astrophysical JournalThe λ 21 cm H i emission that is used to trace the gas-to-dust ratio at high Galactic latitudes has contributions from material beyond the Milky Way disk, with uncertain and likely subsolar metallicity and dust content.

Magnetic Misalignment of Interstellar Dust Filaments
The Astrophysical Journal, 2023 We present evidence for scale-independent misalignment of interstellar dust filaments and magnetic fields. We estimate the misalignment by comparing millimeter-wave dust-polarization measurements from Planck with filamentary structures identified in ...

Tracing Quenching in Nearby Galaxies through Inner Surface Mass Density and Cold Gas Content
The Astrophysical JournalThe inner stellar mass surface density within 1 kpc, Σ _1 , has emerged as a suitable proxy for bulge growth and galaxy quenching. However, the dependence of cold gas content on Σ _1 has not been thoroughly explored.

Where Does the Energy Go during the Interstellar NH3 Formation on Water Ice? A Computational Study
The Astrophysical Journal, 2023 In the coldest (10–20 K) regions of the interstellar medium, the icy surfaces of interstellar grains serve as solid-state supports for chemical reactions.

The Formation of Milky Way “Bones”: Ubiquitous HI Narrow Self-absorption Associated with CO Emission
The Astrophysical Journal LettersLong and skinny molecular filaments running along Galactic spiral arms are known as “bones,” since they make up the skeleton of the Milky Way. However, their origin is still an open question.
