Quantifying the impact of selection effects on FRB DM- relation cosmological inference
Kritti Sharma, Vikram Ravi, Liam Connor +3
Fast Radio Bursts (FRBs) have emerged as powerful probes of baryonic matter in the Universe, offering constraints on cosmological and feedback parameters through their extragalacti…
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…
Probing baryonic feedback and cosmology with 32-point statistic of FRBs and galaxies
Kritti Sharma, Elisabeth Krause, Vikram Ravi +4
The impact of galaxy formation processes on the matter power spectrum is uncertain and may bias cosmological parameters inferred by large-scale structure surveys. Fast Radio Bursts…
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…
Fast Luminous Extragalactic Transients in the VLA Sky Survey: Implications for the rates of Accretion-Induced Collapse Events, Fast Blue Optical Transients and Gamma Ray Burst Afterglows
Kritti Sharma, Vikram Ravi, Dillon Z. Dong +7
Radio wavelengths offer a unique window into high-energy astrophysical phenomena that may be obscured or too rapidly evolving to be captured at other wavelengths. Leveraging data f…
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…
A luminous and hot infrared through X-ray transient at a 5 kpc offset from a dwarf galaxy
Jean J. Somalwar, Vikram Ravi, Raffaella Margutti +20
We are searching for hot, constant-color, offset optical flares in the Zwicky Transient Facility (ZTF) data stream that are from any galaxy in public imaging data from th…
A hydrodynamical simulations-based model that connects the FRB DM--redshift relation to suppression of the matter power spectrum via feedback
Kritti Sharma, Elisabeth Krause, Vikram Ravi +3
Understanding the impact of baryonic feedback on the small-scale (Mpc) matter power spectrum is a key astrophysical challenge, and essential for interpreti…
A Luminous Red Optical Flare and Hard X-ray Emission in the Tidal Disruption Event AT2024kmq
Anna Y. Q. Ho, Yuhan Yao, Tatsuya Matsumoto +30
We present the optical discovery and multiwavelength follow-up observations of AT2024kmq, a likely tidal disruption event (TDE) associated with a supermassive ($M_{\rm BH}\sim 10^{…
A Massive Black Hole 0.8 kpc from the Host Nucleus Revealed by the Offset Tidal Disruption Event AT2024tvd
Yuhan Yao, Ryan Chornock, Charlotte Ward +31
Tidal disruption events (TDEs) that are spatially offset from the nuclei of their host galaxies offer a new probe of massive black hole (MBH) wanderers, binaries, triples, and reco…
