Tracing the Host-Galaxy Environments of FRBs with a New Sample of Localized Sources Detected with the DSA-110
Frank M. Verdi, Vikram Ravi, Myles B. Sherman +7
We characterize the source environments of a sample of fast radio bursts (FRBs) detected with the Deep Synoptic Array (DSA-110). We present new analyses of a sample of 24 FRBs whic…
Deep Synoptic Array Science: Searching for Long Duration Radio Transients with the DSA-110
Myles B. Sherman, Nikita Kosogorov, Casey Law +10
We describe the design and commissioning tests for the DSA-110 Not-So-Fast Radio Burst (NSFRB) search pipeline, a 1.4GHz image-plane single-pulse search sensitive to 134ms-160.8s r…
The Most Luminous Known Fast Blue Optical Transient AT 2024wpp: Unprecedented Evolution and Properties in the Ultraviolet to the Near-Infrared
Natalie LeBaron, Raffaella Margutti, Ryan Chornock +45
We present an extensive photometric and spectroscopic ultraviolet-optical-infrared campaign on the luminous fast blue optical transient (LFBOT) AT 2024wpp over the first ~100 d. AT…
A Correlation Between FRB Dispersion Measure and Foreground Large-Scale Structure
Maryam Hussaini, Liam Connor, Ralf M. Konietzka +4
The distribution of baryons in the Universe remains a fundamental open question in astronomy, and the dispersion measure (DM) of Fast Radio Bursts (FRBs) serves as a valuable tool…
Preferential Occurrence of Fast Radio Bursts in Massive Star-Forming Galaxies
Kritti Sharma, Vikram Ravi, Liam Connor +24
Fast Radio Bursts (FRBs) are millisecond-duration events detected from beyond the Milky Way. FRB emission characteristics favor highly magnetized neutron stars, or magnetars, as th…
A gas-rich cosmic web revealed by the partitioning of the missing baryons
Liam Connor, Vikram Ravi, Kritti Sharma +17
Approximately half of the Universe's dark matter resides in collapsed halos; significantly less than half of the baryonic matter (protons and neutrons) remains confined to halos. A…
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…
Searching for Magnetar Binaries Disrupted by Core-Collapse Supernovae
Myles B. Sherman, Vikram Ravi, Kareem El-Badry +5
Core-collapse Supernovae (CCSNe) are considered the primary magnetar formation channel, with 15 magnetars associated with supernova remnants (SNRs). A large fraction of these shoul…
Morphologies of Bright Complex Fast Radio Bursts with CHIME/FRB Voltage Data
Jakob T. Faber, Daniele Michilli, Ryan Mckinven +23
We present the discovery of twelve thus far non-repeating fast radio burst (FRB) sources, detected by the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope. These so…
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…
Detection of ultra-fast radio bursts from FRB 20121102A
M. P. Snelders, K. Nimmo, J. W. T. Hessels +7
Fast radio bursts (FRBs) are extragalactic transients with typical durations of milliseconds. FRBs have been shown, however, to fluctuate on a wide range of timescales: some show s…
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…
