Global analysis of tensor mode helicity
Anna C. Tsai, Dylan L. Jow, Ue-Li Pen
A detection of helicity in a primordial gravitational-wave background (GWB) would provide compelling evidence for parity violation in the early universe and point toward physics be…
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…
Measuring cosmic expansion with diffractive gravitational scintillation of nanoHertz gravitational waves
Dylan L. Jow, Ue-Li Pen
The recent discovery of ultra-long wavelength gravitational waves through the advent of pulsar timing arrays (PTA) has opened up new avenues for fundamental science. Here we show t…
Re-evaluating evidence for Hawking points in the CMB
Dylan L. Jow, Douglas Scott
We investigate recent claims for a detection of "Hawking points" (positions on the sky with unusually large temperature gradients between rings) in the cosmic microwave background…
