Open Science in Astrophysics: Citation Benefits of Open Code, Open Data, and Open Access
Parth Joshi, Rupert Croft
We analyze the relationship between open-accessibility in data, code, and paper text in astrophysics using a sample of 53,194 peer reviewed papers published between January 2021 an…
Constraining Extragalactic Proper Motion with Gaia Astrometry
Sean Maloney, Tianqing Zhang, Rupert Croft +1
The Solar System's secular motion with respect to the cosmic microwave background (CMB) rest frame is inferred from the CMB dipole and should induce a tiny, coherent apparent drift…
Forecasting the Detection of Lyman-Alpha Forest Weak Lensing from the Dark Energy Spectroscopic Instrument and Other Future Surveys
Patrick Shaw, Rupert A. C. Croft, R. Benton Metcalf
The apparent angular positions of quasars are deflected on the sky by the gravitational field sourced by foreground matter. This weak lensing effect is measurable through the disto…
Weak Lensing the non-Linear Ly-alpha Forest
Patrick Shaw, Rupert A. C. Croft, R. Benton Metcalf
We evaluate the performance of the Lyman- forest weak gravitational lensing estimator of Metcalf et al. on forest data from hydrodynamic simulations and ray-traced simulated le…
