ALMA observations reveal no preferred outflow--filament and outflow--magnetic field orientations

T. Baug, Ke Wang, Tie Liu +12

We present a statistical study on the orientation of outflows with respect to large-scale filaments and the magnetic fields. Although filaments are widely observed toward Galactic…

Revealing The CO X-factor In Dark Molecular Gas through Sensitive ALMA Absorption Observations

Gan Luo, Di Li, Ningyu Tang +11

Carbon-bearing molecules, particularly CO, have been widely used as tracers of molecular gas in the interstellar medium (ISM). In this work, we aim to study the properties of molec…

Metallicity and -element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE

Christian R. Hayes, Steven R. Majewski, Sten Hasselquist +27

Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Obs…

Chemical properties of two dense cores in a Planck Galactic Cold Clump G168.72-15.48

Mengyao Tang, J. X. Ge, Sheng-Li Qin +8

To deepen our understanding of the chemical properties of the Planck Galactic Cold Clump (PGCC) G168.72-15.48, we performed observations of nine molecular species, namely, \ce{c-C3…

Slicing the cool circumgalactic medium along the major-axis of a star-forming galaxy at

S. Lopez, N. Tejos, L. F. Barrientos +13

We present spatially-resolved echelle spectroscopy of an intervening MgII-FeII-MgI absorption-line system detected at toward the giant gravitational arc PSZ1…

The Hi-GAL catalogue of dusty filamentary structures in the Galactic Plane

E. Schisano, S. Molinari, D. Elia +27

The recent data collected by {\it Herschel} have confirmed that interstellar structures with filamentary shape are ubiquitously present in the Milky Way. Filaments are thought to b…
