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…
Baryonification III: An accurate analytical model for the dispersion measure probability density function of fast radio bursts
