Devouring the Milky Way Satellites: Modeling Dwarf Galaxies with Galacticus
The Astrophysical Journal, 2023 Dwarf galaxies are ubiquitous throughout the universe and are extremely sensitive to various forms of internal and external feedback. Over the last two decades, the census of dwarf galaxies in the Local Group and beyond has increased markedly.

The Effects of Dark Matter and Baryonic Physics on the Milky Way Subhalo Population in the Presence of the Large Magellanic Cloud [PDF]
Astrophysical Journal Letters, 2021 Abstract Given recent developments in our understanding of the Large Magellanic Cloud's (LMC) impact on the Milky Way's (MW) dark matter subhalo population, we compare the signatures of dark matter and baryonic physics on subhalos in MW systems with realistic LMC analogs.

Assessing the physical reality of Milky Way open cluster candidates
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We report results on the analysis of 11 new Milky Way open cluster candidates, recently discovered from the detection of stellar overdensities in the Vector Point diagram, by employing Xtreme deconvolution Gaussian mixture models.

PHYSICAL PROPERTIES OF MOLECULAR CLOUDS FOR THE ENTIRE MILKY WAY DISK [PDF]
The Astrophysical Journal, 2017 ABSTRACT This study presents a catalog of 8107 molecular clouds that covers the entire Galactic plane and includes 98% of the 12CO emission observed within . The catalog was produced using a hierarchical cluster identification method applied to the result of a Gaussian ...

The LEGO Large Program: Constraining the Physics of Line Emission in Galaxy Observations [PDF]
EPJ Web of Conferences, 2022 The IRAM Large Program LEGO studies molecular clouds in the Milky Way to constrain the physics controlling molecular line emission in galaxies. This is done by imaging two dozen clouds with setups that provide continuous spectral coverage of about 85–115

THE MILKY WAY PROJECT AND ATLASGAL: THE DISTRIBUTION AND PHYSICAL PROPERTIES OF COLD CLUMPS NEAR INFRARED BUBBLES [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present a statistical study of the distribution and physical properties of cold, dense material in and around the inner Galactic Plane near-infrared bubbles as cataloged by the Milky Way Project citizen scientists. Using data from the Atacama Pathfinder Experiment (APEX) Telescope Large Area Survey of the Galaxy 870 μm survey,

On the physical mechanisms governing the cloud lifecycle in the Central Molecular Zone of the Milky Way [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We apply an analytic theory for environmentally-dependent molecular cloud lifetimes to the Central Molecular Zone of the Milky Way. Within this theory, the cloud lifetime in the Galactic centre is obtained by combining the time-scales for gravitational instability, galactic shear, epicyclic perturbations and cloud-cloud collisions.

Evidence of a Cloud–Cloud Collision from Overshooting Gas in the Galactic Center
The Astrophysical Journal, 2023 The Milky Way is a barred spiral galaxy with bar lanes that bring gas toward the Galactic center. Gas flowing along these bar lanes often overshoots, and instead of accreting onto the Central Molecular Zone (CMZ), it collides with the bar lane on the ...

On the physical size of the Milky Way globular cluster NGC 7089 (M2)
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We study the outer regions of the Milky Way globular cluster NGC 7089 based on new Dark Energy Camera observations. The resulting background-cleaned stellar density profile reveals the existence of an extended envelope. We confirm previous results that cluster stars are found out up to ∼1° from the cluster’s centre, which is ...

The role of galactic dynamics in shaping the physical properties of giant molecular clouds in Milky Way-like galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We examine the role of the large-scale galactic-dynamical environment in setting the properties of giant molecular clouds in Milky Way-like galaxies. We perform three high-resolution simulations of Milky Way-like discs with the moving-mesh hydrodynamics code arepo, yielding a statistical sample of ${\sim}80\, 000$ giant ...
