Spitzer + VLTI-GRAVITY Measure the Lens Mass of a Nearby Microlensing Event
Weicheng Zang, Subo Dong, Andrew Gould +24
We report the lens mass and distance measurements of the nearby microlensing event TCP J05074264+2447555. We measure the microlens parallax vector using Spitzer and gro…

Kristine Spekkens, Cynthia Chiang, Roland Kothes +57
This white paper submitted for the 2020 Canadian Long-Range Planning process (LRP2020) presents the prospects for Canada and the Square Kilometre Array (SKA) from 2020-2030, focuss…
LRP 2020 Whitepaper: The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD)
K. Vanderlinde, K. Bandura, L. Belostotski +20
The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation radio telescope, proposed for construction to start immediately. CHORD is a pan-Canadian…
Improving the Epoch of Reionization Power Spectrum Results from Murchison Widefield Array Season 1 Observations
N. Barry, M. Wilensky, C. M. Trott +27
Measurements of 21 cm Epoch of Reionization (EoR) structure are subject to systematics originating from both the analysis and the observation conditions. Using 2013 data from the M…
Astronomy in a Low-Carbon Future
Christopher D. Matzner, Nicolas B. Cowan, René Doyon +12
The global climate crisis poses new risks to humanity, and with them, new challenges to the practices of professional astronomy. Avoiding the more catastrophic consequences of glob…
The Kelvin-Helmholtz instability and smoothed particle hydrodynamics
Terrence S. Tricco
There has been interest in recent years to assess the ability of astrophysical hydrodynamics codes to correctly model the Kelvin-Helmholtz instability. Smoothed particle hydrodynam…
