DOI: 10.1016/j.newast.2018.07.008
Abstract: Abstract In search of the scenario of the star formation process, fragmentation of molecular clouds has been modelled under two different conditions. In the first case, thermal instability along with an equation of state with… read more here.

DOI: 10.1051/0004-6361/201731833
Abstract: Context Previous attempts at segmenting molecular line maps of molecular clouds have focused on using position-position-velocity data cubes of a single molecular line to separate the spatial components of the cloud. In contrast, wide field… read more here.

DOI: 10.1088/1674-4527/acd58b
Abstract: We present an analysis of 288 young stellar objects (YSOs) in the Perseus Molecular Cloud that have well defined g and r-band lightcurves from the Zwicky Transient Facility. Of the 288 YSOs, 238 sources (83%… read more here.

DOI: 10.1093/mnras/staa468
Abstract: Complex turbulent motions of magnetized gas are ubiquitous in the interstellar medium (ISM). The source of this turbulence, however, is still poorly understood. Previous work suggests that compression caused by supernova shockwaves, gravity, or cloud… read more here.

DOI: 10.1093/mnras/stx532
Abstract: Using N-body/gasdynamic simulations of a Milky Way-like galaxy we analyse a Kennicutt-Schmidt relation, $\Sigma_{SFR} \propto \Sigma_{gas}^N$, at different spatial scales. We simulate synthetic observations in CO lines and UV band. We adopt the star formation… read more here.
