Paper published by Guadalupe Tovar Mendoza and DiRAC’s Associate Director James R. A. Davenport. Stellar variability is a limiting factor for planet detection and characterization, particularly around active M-type stars. Here we revisit one of the most active stars from the Kepler mission.

January 12, 2022 | DiRAC NEWS
Published paper by Melissa Graham Supernovae are the explosions of stars that can be seen across vast distances, appearing as new bright points of light in optical images of the sky, even when the original star was far too faint to be detected. When different types of stars explode (e.g., low-mass and high-mass) they cause […]

Mapping the “Cosmic Web”
December 17, 2021 | Research
A tenet of modern cosmology is the existence of the “cosmic web”, a vast filamentary structure formed via the collapse of matter due to gravity. This structure is ubiquitous in cosmological simulations yet challenging to observe due to its diffuse nature. Recently, a new technique was developed which is inspired by the growth and movement […]

Sifting through the Static
November 22, 2021 | DiRAC News
Trans-Neptunian objects provide a window into the history of the solar system, but they can be challenging to observe due to their distance from the Sun and relatively low brightness. In the recently published paper, Sifting through the Static: Moving Object Detection in Difference Images, DiRAC researchers report the detection of 75 moving objects that […]

ParSNIP: Using deep learning to identify supernovae and probe dark energy
November 16, 2021 | DiRAC NEWS
DiRAC researchers are heavily involved in building the Vera C. Rubin Observatory, a new facility that is currently under construction in Chile. This observatory will feature the 8.4 meter Simonyi Survey Telescope and the world’s largest CCD camera which will scan the entire visible sky every three nights. It will discover and observe millions of […]
