We present the host galaxies of four apparently nonrepeating fast radio bursts (FRBs), FRB
20181223C, FRB 20190418A, FRB 20191220A, and FRB 20190425A, reported in the first …

Fast radio bursts (FRBs) are a powerful and mysterious new class of transients that are
luminous enough to be detected at cosmological distances. By associating FRBs to host …

We investigate the contribution of host galaxies to the overall dispersion measures (DMs) for
fast radio bursts (FRBs) using the Feedback in Realistic Environments (FIRE-2) …

Exploring the concept of a massive photon has been an important area in astronomy and
physics. If photons have mass, their propagation in nonvacuum space would be affected by …

We present a search for host galaxy associations for the third set of repeating fast radio burst
(FRB) sources discovered by the CHIME/FRB Collaboration. Using the∼ 1'CHIME/FRB …

Localization of fast radio bursts (FRBs) to arcsecond and subarcsecond precision maximizes
their potential as cosmological probes. To that end, FRB detection instruments are deploying …

Understanding physical mechanisms relies on the accurate determination of fundamental
constants, although inherent limitations in experimental techniques introduce uncertainties …

We present a search for transient radio sources on time-scales of seconds to hours at 144
MHz using the LOFAR Two-metre Sky Survey (LoTSS). This search is conducted by …

We present observations from the Gemini Multi-Conjugate Adaptive Optics System/Gemini
South Adaptive Optics Imager at Gemini South of five fast radio burst (FRB) host galaxies of …

Fast Radio Bursts (FRBs) are millisecond dispersed radio pulses of predominately extra-
galactic origin. Although originally discovered at GHz frequencies, most FRBs have been …
