Kavli Affiliate: Richard Kessler | First 5 Authors: Richard Kessler, Dan Scolnic, , , | Summary: We present a new technique to create a bin-averaged Hubble Diagram (HD) from photometrically identified SN~Ia data. The resulting HD is corrected for selection biases and contamination from core collapse (CC) SNe, and can be used to infer cosmological […]
Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Yu-Wei Liao, Tzu-Ching Chang, Cheng-Yu Kuo, Kiyoshi Wesley Masui, Niels Oppermann | Summary: Polarization leakage of foreground synchrotron emission is a critical issue in HI intensity mapping experiments. While the sought-after HI emission is unpolarized, polarized foregrounds such as Galactic and extragalactic synchrotron radiation, if coupled […]
Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ryosuke Itoh, Krzysztof Nalewajko, Yasushi Fukazawa, Makoto Uemura, Yasuyuki T. Tanaka | Summary: Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energies […]
Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Akifumi Seko, Kouji Ohta, Kiyoto Yabe, Bunyo Hatsukade, Masayuki Akiyama | Summary: We constrain the rate of gas inflow into and outflow from a main-sequence star-forming galaxy at z~1.4 by fitting a simple analytic model for the chemical evolution in a galaxy to the observational data of […]

Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Vanessa P. Bailey, Lisa A. Poyneer, Bruce A. Macintosh, Dmitry Savransky, Jason J. Wang | Summary: The Gemini Planet Imager is a high-contrast near-infrared instrument specifically designed to image exoplanets and circumstellar disks over a narrow field of view. We use science data and AO telemetry […]
Kavli Affiliate: Daniel Akerib | First 5 Authors: Jim Alexander, Marco Battaglieri, Bertrand Echenard, Rouven Essig, Matthew Graham | Summary: This report, based on the Dark Sectors workshop at SLAC in April 2016, summarizes the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak-scale, the status of this […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Elise Jennings, Maeve Madigan, , , | Summary: Given the complexity of modern cosmological parameter inference where we are faced with non-Gaussian data and noise, correlated systematics and multi-probe correlated data sets, the Approximate Bayesian Computation (ABC) method is a promising alternative to traditional Markov Chain Monte […]
Kavli Affiliate: Masaki Yamashita | First 5 Authors: Jing Liu, Masaki Yamashita, Arun Kumar Soma, , | Summary: A light yield of 20.4 $pm$ 0.8 photoelectrons/keV was achieved with an undoped CsI crystal coupled directly to a photomultiplier tube at 77 Kelvin. This is by far the largest yield in the world achieved with CsI […]
Kavli Affiliate: John W. Belcher | First 5 Authors: Hui Li, Chi Wang, Jiansen He, Lingqian Zhang, John D. Richardson | Summary: Nonlinear cascade of low-frequency Alfvenic fluctuations (AFs) is regarded as one candidate of the energy sources to heat plasma during the non-adiabatic expansion of interplanetary coronal mass ejections (ICMEs). However, AFs inside ICMEs […]
