ALMA observations of fragmentation, sub-structure, and protostars in high-mass starless clump candidates
Brian E. Svoboda, Yancy L. Shirley, Alessio Traficante +7
(Abridged) The initial physical conditions of high-mass stars and protoclusters remain poorly characterized. To this end we present the first targeted ALMA 1.3mm continuum and spec…
ALMA Resolves 30 Doradus: Sub-parsec Molecular Cloud Structure Near the Closest Super-Star Cluster
Remy Indebetouw, Crystal Brogan, C. -H. Rosie Chen +15
We present ALMA observations of 30 Doradus -- the highest resolution view of molecular gas in an extragalactic star formation region to date (~0.4pc x 0.6pc). The 30Dor-10 cloud no…
ALMAGAL VII. Cataloging Hierarchical Mass Structure from Cores to Clumps across the Galactic Disk
Jennifer Wallace, Taevis Kolz, Cara Battersby +42
Investigating the multi-scale fragmentation of dense clumps into compact cores is essential for understanding the processes that govern the initial distribution of mass in stellar…
VLBI20-30: a scientific roadmap for the next decade -- The future of the European VLBI Network
Tiziana Venturi, Zsolt Paragi, Michael Lindqvist +77
This white paper describes the science case for Very Long Baseline Interferometry (VLBI) and provides suggestions towards upgrade paths for the European VLBI Network (EVN). The EVN…
Multi-epoch VLBI of a double maser super burst
Ross A. Burns, Olga Bayandina, Gabor Orosz +20
In a rare and spectacular display, two well-known massive star forming regions, W49N and G25.65+1.05, recently underwent maser 'super burst' - their fluxes suddenly increasing abov…
Realizing the Unique Potential of ALMA to Probe the Gas Reservoir of Planet Formation
L. Ilsedore Cleeves, Ryan Loomis, Richard Teague +21
Understanding the origin of the astonishing diversity of exoplanets is a key question for the coming decades. ALMA has revolutionized our view of the dust emission from protoplanet…
ALMA maps the Star-Forming Regions in a Dense Gas Disk at z~3
Mark Swinbank, Simon Dye, James Nightgale +14
We exploit long-baseline ALMA sub-mm observations of the lensed star-forming galaxy SDP 81 at z=3.042 to investigate the properties of inter-stellar medium on scales of 50-100pc. T…
Random Processes With Power Law Spectral Density
Robert Kimberk, Keara Carter, Todd Hunter
A statistical model of discrete finite length random processes with negative power law spectral densities is presented. The definition of terms is followed by a description of the…
Next Generation Very Large Array Memo No. 7 Science Working Group 2: "Galaxy Ecosystems": The Matter Cycle in and Around Galaxies
Adam K. Leroy, Eric Murphy, Lee Armus +19
This white paper discusses how a "next-generation" Very Large Array (ngVLA) operating in the frequency range 1-116 GHz could be a groundbreaking tool to study the detailed astrophy…
Young stellar clusters and star formation throughout the Galaxy
Eric Feigelson, Fred Adams, Lori Allen +22
Most stars are born in rich young stellar clusters (YSCs) embedded in giant molecular clouds. The most massive stars live out their short lives there, profoundly influencing their…
Distributed star formation throughout the Galactic Center cloud Sgr B2
A. G. Ginsburg, John Bally, Ashley Barnes +23
We report ALMA observations with resolution " at 3 mm of the extended Sgr B2 cloud in the Central Molecular Zone (CMZ). We detect 271 compact sources, most of which are…
