Proper motion measurements for stars up to $100$ kpc with Subaru HSC and SDSS Stripe 82

Posted by klaurent Tokyo

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Tian Qiu, Wenting Wang, Masahiro Takada, Naoki Yasuda, Željko Ivezić | Summary: We present proper motion measurements for more than $0.55$ million main-sequence stars, by comparing astrometric positions of matched stars between the multi-band imaging datasets from the Hyper Suprime-Cam (HSC) Survey and the SDSS Stripe 82. […]

Prospects for High-Elevation Radio Detection of >100 PeV Tau Neutrinos

Posted by Chicago

Kavli Affiliate: Abigail Vieregg | First 5 Authors: Stephanie Wissel, Andrés Romero-Wolf, Harm Schoorlemmer, Washington R. Carvalho Jr., Jaime Alvarez-Muñiz | Summary: Tau neutrinos are expected to comprise roughly one third of both the astrophysical and cosmogenic neutrino flux, but currently the flavor ratio is poorly constrained and the expected flux at energies above $10^{17}$ […]
