COLDz: Deep 34 GHz Continuum Observations and Free-free Emission in High-redshift Star-forming Galaxies
H. S. B. Algera, J. A. Hodge, D. Riechers +9
The high-frequency radio sky has historically remained largely unexplored due to the typical faintness of sources in this regime, and the modest survey speed compared to observatio…
A Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE).IX. The effects of ram pressure stripping down to the scale of individual HII regions in the dwarf galaxy IC 3476
A. Boselli, A. Lupi, B. Epinat +25
We study the IB(s)m galaxy IC 3476 observed in the context of VESTIGE, a blind narrow-band Halpha+[NII] imaging survey of the Virgo cluster. The deep narrow-band (NB) image reveals…
Prospects for Galactic and stellar astrophysics with asteroseismology of giant stars in the Continuous Viewing Zones and beyond
J. Ted Mackereth, Andrea Miglio, Yvonne Elsworth +30
The NASA- mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We present a first look at the prospects for…
Gaia Early Data Release 3 -- Catalogue validation
C. Fabricius, X. Luri, F. Arenou +33
The third Gaia data release is published in two stages. The early part, Gaia EDR3, gives very precise astrometric and photometric properties for nearly two billion sources together…
The Fundamental Plane of Massive Quiescent Galaxies at z~2
Mikkel Stockmann, Inger Jørgensen, Sune Toft +11
We examine the Fundamental Plane (FP) and mass-to-light ratio () scaling relations using the largest sample of massive quiescent galaxies at to date. The FP ($r_{e…
MIGHTEE: Are giant radio galaxies more common than we thought?
J. Delhaize, I. Heywood, M. Prescott +31
We report the discovery of two new giant radio galaxies (GRGs) using the MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) survey. Both GRGs were found within a…
Observations of magnetic fields surrounding LkH 101 taken by the BISTRO survey with JCMT-POL-2
Nguyen Bich Ngoc, Pham Ngoc Diep, Harriet Parsons +146
We report the first high spatial resolution measurement of magnetic fields surrounding LkH 101, a part of the Auriga-California molecular cloud. The observations were taken with…
Thermal and turbulent properties of the Warm Neutral Medium in the solar neighborhood
Antoine Marchal, Marc-Antoine Miville-Deschênes
The transition from the diffuse warm neutral medium (WNM) to the dense cold neutral medium (CNM) is what set the initial conditions to the formation of molecular clouds. The proper…
SLITronomy: towards a fully wavelet-based strong lensing inversion technique
A. Galan, A. Peel, R. Joseph +2
Strong gravitational lensing provides a wealth of astrophysical information on the baryonic and dark matter content of galaxies. It also serves as a valuable cosmological probe by…
