A Relationship Between Fast Radio Burst Dispersion Measure and Host Galaxy Inclination

Lachlan Marnoch, Stuart D. Ryder, Sunil Simha +9

It is commonly thought that fast radio bursts (FRBs) trace star formation, and that they are produced by magnetars. Both hypotheses imply that their sources are hosted primarily (b…

Pinpointing the cosmic web between massive galaxy clusters I. The incidence of HI and OVI as WHIM tracers

Karen Martínez-Acosta, Nicolas Tejos, Ismael Pessa +6

At redshift z<1, the CDM paradigm predicts that 40-50\% of baryons reside in the warm-hot intergalactic medium (WHIM) within cosmic web filaments. Characterizing the physi…

A spatially resolved view of Fast Radio Burst host metallicities with Integral-field Spectroscopy

Sunil Simha, Hsiao-Wen Chen, Wen-fai Fong +15

Magnetar sources are the leading theory for Fast Radio Burst (FRB) progenitors. If magnetars are indeed the dominant sources, we may thus expect any metallicity preference for magn…

Star formation and morphological trends in the Antlia cluster: Probing environmental influence out to 5R200

Ciria Lima-Dias, Antonela Monachesi, Gissel P. Montaguth +48

Galaxy evolution in dense environments such as clusters is strongly affected by environmental processes that can alter both morphology and star formation activity. We investigate t…

PIFFLE: Characterizing the Foreground Contributions from 4 Decades in Halo Mass to the FRB20230907D Dispersion Measure

Qi Guo, Khee-Gan Lee, Sunil Simha +10

We characterize the foreground environment of FRB20230907D, localized to a galaxy at , which has an observed dispersion measure of ${\rm DM}_{\rm obs}=1031~{\rm pc~cm^{-3}…

Two new highly scattered fast radio bursts: evidence for scatter broadening by the circumsource medium

Joscha N. Jahns-Schindler, Keith W. Bannister, Adam T. Deller +17

We found two highly scattered Fast Radio Bursts (FRBs) during commissioning of the Commensal Realtime ASKAP Fast Transient COherent (CRACO) backend. FRB 240210D and FRB 240312D hav…
