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…
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…
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 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 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…
