A Heavily Scattered Fast Radio Burst Is Viewed Through Multiple Galaxy Halos
Jakob T. Faber, Vikram Ravi, Stella Koch Ocker +16
We present a multi-wavelength study of the apparently non-repeating, heavily scattered fast radio burst, FRB 20221219A, detected by the Deep Synoptic Array 110 (DSA-110). The burst…
Deep Synoptic Array Science: Implications of Faraday Rotation Measures of Localized Fast Radio Bursts
Myles B. Sherman, Liam Connor, Vikram Ravi +20
Faraday rotation measures (RMs) of fast radio bursts (FRBs) offer the prospect of directly measuring extragalactic magnetic fields. We present an analysis of the RMs of ten as yet…
Deep Synoptic Array Science: Polarimetry of 25 New Fast Radio Bursts Provides Insights into their Origins
Myles B. Sherman, Liam Connor, Vikram Ravi +20
We report on a full-polarization analysis of the first 25 as yet non-repeating FRBs detected at 1.4 GHz by the 110-antenna Deep Synoptic Array (DSA-110) during commissioning observ…
Deep Synoptic Array Science: First FRB and Host Galaxy Catalog
C. J. Law, K. Sharma, V. Ravi +19
Fast Radio Bursts (FRBs) are a powerful and mysterious new class of transient that are luminous enough to be detected at cosmological distances. By associating FRBs to host galaxie…
COMAP Early Science: VIII. A Joint Stacking Analysis with eBOSS Quasars
Delaney A. Dunne, Kieran A. Cleary, Patrick C. Breysse +22
We present a new upper limit on the cosmic molecular gas density at obtained using the first year of observations from the CO Mapping Array Project (COMAP). COMAP data…
Deep Synoptic Array science: Two fast radio burst sources in massive galaxy clusters
Liam Connor, Vikram Ravi, Morgan Catha +21
The hot gas that constitutes the intracluster medium (ICM) has been studied at X-ray and millimeter/sub-millimeter wavelengths (Sunyaev-Zeldovich effect) for decades. Fast radio bu…
Deep Synoptic Array science: A massive elliptical host among two galaxy-cluster fast radio bursts
Kritti Sharma, Jean Somalwar, Casey Law +20
The stellar population environments associated with fast radio burst (FRB) sources provide important insights for developing their progenitor theories. We expand the diversity of k…
Deep Synoptic Array science: a 50 Mpc fast radio burst constrains the mass of the Milky Way circumgalactic medium
Vikram Ravi, Morgan Catha, Ge Chen +21
We present the Deep Synoptic Array (DSA-110) discovery and interferometric localization of the so far non-repeating FRB 20220319D. The FRB originates in a young, rapidly star-formi…
Deep Synoptic Array science I: discovery of the host galaxy of FRB 20220912A
Vikram Ravi, Morgan Catha, Ge Chen +25
We report the detection and interferometric localization of the repeating fast radio burst (FRB) source FRB 20220912A during commissioning observations with the Deep Synoptic Array…
Molecular tracers of planet formation in the atmospheres of hot Jupiters
Richard Hobbs, Oliver Shorttle, Nikku Madhusudhan
The atmospheric chemical composition of a hot Jupiter can lead to insights into where in its natal protoplanetary disk it formed and its subsequent migration pathway. We use a 1-D…
COMAP Early Science: II. Pathfinder Instrument
James W. Lamb, Kieran A. Cleary, David P. Woody +32
Line intensity mapping (LIM) is a new technique for tracing the global properties of galaxies over cosmic time. Detection of the very faint signals from redshifted carbon monoxide…
COMAP Early Science: I. Overview
Kieran A. Cleary, Jowita Borowska, Patrick C. Breysse +40
The CO Mapping Array Project (COMAP) aims to use line intensity mapping of carbon monoxide (CO) to trace the distribution and global properties of galaxies over cosmic time, back t…
COMAP Early Science: VII. Prospects for CO Intensity Mapping at Reionization
Patrick C. Breysse, Dongwoo T. Chung, Kieran A. Cleary +29
We introduce COMAP-EoR, the next generation of the Carbon Monoxide Mapping Array Project aimed at extending CO intensity mapping to the Epoch of Reionization. COMAP-EoR supplements…
COMAP Early Science: VI. A First Look at the COMAP Galactic Plane Survey
Thomas J. Rennie, Stuart E. Harper, Clive Dickinson +29
We present early results from the COMAP Galactic Plane Survey conducted between June 2019 and April 2021, spanning in Galactic longitude and $|b|<1.\!\!^{\…
COMAP Early Science: V. Constraints and Forecasts at

Hydroxide salts in the clouds of Venus: their effect on the sulfur cycle and cloud droplet pH
Paul B. Rimmer, Sean Jordan, Tereza Constantinou +4
The depletion of SO and HO in and above the clouds of Venus (45 -- 65 km) cannot be explained by known gas-phase chemistry and the observed composition of the atmosphere. W…
