The THESAN project: galaxy sizes during the epoch of reionization

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Josh Borrow, Yongao Hu, Evan Erickson | Summary: We investigate galaxy sizes at redshift $zgtrsim 6$ with the cosmological radiation-magneto-hydrodynamic simulation suite THESAN(-HR). These simulations simultaneously capture the reionization of the large-scale intergalactic medium and resolved galaxy properties. The intrinsic size ($r^{ast}_{1/2}$) of […]

A demonstration of the effect of fringe-rate filtering in the Hydrogen Epoch of Reionization Array delay power spectrum pipeline

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Hugh Garsden, Philip Bull, Mike Wilensky, Zuhra Abdurashidova, Tyrone Adams | Summary: Radio interferometers targeting the 21cm brightness temperature fluctuations at high redshift are subject to systematic effects that operate over a range of different timescales. These can be isolated by designing appropriate Fourier filters that […]

High-cadence Timing of Binary Pulsars with CHIME

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Chia Min Tan, Emmanuel Fonseca, Kathryn Crowter, Fengqiu Adam Dong, Victoria M. Kaspi | Summary: We performed near-daily observations on the binary pulsars PSR J0218+4232, PSR J1518+4904 and PSR J2023+2853 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). For the first time, we detected the Shapiro […]

Ephemeris Matching Reveals False Positive Validated and Candidate Planets from the K2 Mission

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Drake A. Lehmann, Andrew Vanderburg, , , | Summary: Data from the Kepler space telescope have led to the discovery of thousands of planet candidates. Most of these candidates are likely to be real exoplanets, but a significant number of false positives still contaminate the sample, especially […]

CHIME/FRB Outriggers: KKO Station System and Commissioning Results

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adam E. Lanman, Shion Andrew, Mattias Lazda, Vishwangi Shah, Mandana Amiri | Summary: Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger program aims to add VLBI-localization capabilities […]

The TESS-Keck Survey XXI: 13 New Planets and Homogeneous Properties for 21 Subgiant Systems

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Ashley Chontos, Daniel Huber, Samuel K. Grunblatt, Nicholas Saunders, Joshua N. Winn | Summary: We present a dedicated transit and radial velocity survey of planets orbiting subgiant stars observed by the TESS Mission. Using $sim$$16$ nights on Keck/HIRES, we confirm and characterize $12$ new transiting planets — […]
