A stochastic forward model for the intergalactic dispersion-measure distribution of Fast Radio Bursts
Jéferson A. S. Fortunato, Valerio Marra, Wiliam S. Hipólito-Ricaldi +1
Fast Radio Bursts probe ionised baryons through their observed dispersion measures. We present \turbofrb, a semi-analytic stochastic forward model for the intergalactic dispersion-…
Probing the Baryon Distribution with Fast Radio Bursts
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +12
Baryonic feedback redistributes matter on small to mid cosmological scales, ultimately limiting inferences from Stage IV galaxy surveys. Direct baryon tracers are crucial for recov…
Fast Radio Bursts as Cosmological Probes
Manisha Caleb, Jéferson A. S. Fortunato, Steffen Hagstotz +14
Fast radio bursts (FRBs) are brief, coherent radio pulses of extragalactic origin. They typically last from microseconds to milliseconds and have energies large enough to be visibl…
Testing the cosmic distance-duality relation with localized fast radio bursts: a cosmological model-independent study
Jéferson A. S. Fortunato, Surajit Kalita, Amanda Weltman
We test the Etherington cosmic distance-duality relation (CDDR), by comparing Type Ia supernova (SNIa) luminosity-distance information from the Pantheon+ compilation with an angula…
