An Hi-absorption-selected Cold Rotating Disk Galaxy at z ≈ 2.193
The Astrophysical Journal LettersWe have used the Atacama Large Millimeter/submillimeter Array to map CO(3–2) emission from a galaxy, DLA-B1228g, associated with the high-metallicity damped Ly α absorber at z ≈ 2.1929 toward the QSO PKS B1228–113. At an angular resolution of ≈0.″32 × 0.″

The Impact of Foregrounds on Dark Ages Measurements with the Highly Redshifted 21 cm Line
The Astrophysical JournalStudies of the cosmic dark ages (30 ≲ z ≲ 150) using the highly redshifted 21 cm line of neutral hydrogen offer unparalleled amounts of cosmological information, and recent years have seen the refinement of concepts for such experiments (e.g., CoDEX ...

Radio Frequency Interference: Simulations for Radio Interferometry Arrays
, 2021 Radio Frequency Interference (RFI) is a massive problem for radio observatories around the world. Due to the growth of telecommunications and air travel RFI is increasing exactly when the world's radio telescopes are increasing significantly in sensitivity, making RFI one of the most pressing problems for astronomy in the era of the Square Kilometre ...
