Astrochemical modelling of infrared dark clouds
Negar Entekhabi, Jonathan C. Tan, Giuliana Cosentino +8
Infrared dark clouds (IRDCs) are cold, dense regions of the interstellar medium (ISM) that are likely to represent the initial conditions for massive star formation. It is thus imp…
The "Maggie" filament: Physical properties of a giant atomic cloud
J. Syed, J. D. Soler, H. Beuther +19
The atomic phase of the interstellar medium plays a key role in the formation process of molecular clouds. Due to the line-of-sight confusion in the Galactic plane that is associat…
A wind-blown bubble in the Central Molecular Zone cloud G0.253+0.016
J. D. Henshaw, M. R. Krumholz, N. O. Butterfield +16
G0.253+0.016, commonly referred to as "the Brick" and located within the Central Molecular Zone, is one of the densest ( cm) molecular clouds in the Galaxy…
The PHANGS-MUSE survey -- Probing the chemo-dynamical evolution of disc galaxies
Eric Emsellem, Eva Schinnerer, Francesco Santoro +45
We present the PHANGS-MUSE survey, a programme using the MUSE IFS at the ESO VLT to map 19 massive nearby (D < 20 Mpc) star-forming disc galaxi…
Stellar structures, molecular gas, and star formation across the PHANGS sample of nearby galaxies
M. Querejeta, E. Schinnerer, S. Meidt +32
We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct morphological masks of sub-galactic environments based on Spitzer 3.6 micron images. At the…
Clustered Star Formation in the center of NGC 253 Contributes to Driving the Ionized Nuclear Wind
E. A. C. Mills, M. Gorski, K. L. Emig +12
We present new 3 mm observations of the ionized gas toward the nuclear starburst in the nearby (D ~ 3.5 Mpc) galaxy NGC 253. With ALMA, we detect emission from the H40-alpha and He…
The centres of M83 and the Milky Way: opposite extremes of a common star formation cycle
Daniel Callanan, Steven N. Longmore, J. M. Diederik Kruijssen +8
In the centres of the Milky Way and M83, the global environmental properties thought to control star formation are very similar. However, M83's nuclear star formation rate (SFR), a…
PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-Forming Galaxies
Adam K. Leroy, Eva Schinnerer, Annie Hughes +69
We present PHANGS-ALMA, the first survey to map CO J=2-1 line emission at ~1" ~ 100pc spatial resolution from a representative sample of 90 nearby (d<~20 Mpc) galaxies that lie on…
PHANGS-ALMA Data Processing and Pipeline
Adam K. Leroy, Annie Hughes, Daizhong Liu +65
We describe the processing of the PHANGS-ALMA survey and present the PHANGS-ALMA pipeline, a public software package that processes calibrated interferometric and total power data…
The complex multi-scale structure in simulated and observed emission maps of the proto-cluster cloud G0.253+0.016 (`the Brick')
Maya A. Petkova, J. M. Diederik Kruijssen, A. Louise Kluge +6
The Central Molecular Zone (CMZ; the central ~ 500 pc of the Milky Way) hosts molecular clouds in an extreme environment of strong shear, high gas pressure and density, and complex…
The organization of cloud-scale gas density structure: high resolution CO vs. 3.6 m brightness contrasts in nearby galaxies
Sharon E. Meidt, Adam K. Leroy, Miguel Querejeta +29
In this paper we examine the factors that shape the distribution of molecular gas surface densities on the 150 pc scale across 67 morphologically diverse star-forming galaxies in t…
ALMA-IRDC II. First high-angular resolution measurements of the 14N/15N ratio in a large sample of infrared-dark cloud cores
F. Fontani, A. T. Barnes, P. Caselli +6
The 14N/15N ratio in molecules exhibits a large variation in star-forming regions, especially when measured from N2H+ isotopologues. However, there are only a few studies performed…
ALMA-IRDC: Dense gas mass distribution from cloud to core scales
A. T. Barnes, J. D. Henshaw, F. Fontani +15
Infrared dark clouds (IRDCs) are potential hosts of the elusive early phases of high-mass star formation (HMSF). Here we conduct an in-depth analysis of the fragmentation propertie…
Measurement of the very rare decay
NA62 Collaboration
The NA62 experiment reports the branching ratio measurement BR at 68% CL, base…
Star formation in 'the Brick': ALMA reveals an active proto-cluster in the Galactic centre cloud G0.253+0.016
Daniel L. Walker, Steven N. Longmore, John Bally +16
G0.253+0.016, aka 'the Brick', is one of the most massive (> 10^5 Msun) and dense (> 10^4 cm-3) molecular clouds in the Milky Way's Central Molecular Zone. Previous observations ha…
