Tatooine Orbits

Published: May 04, 2023

The planet Tatooine in Star Wars orbits has two suns. We want to see if it’s possible for Tattoine to exist in the real world by simulating its orbit.

The Earth’s favourite New year, Nowruz

Published: April 03, 2024

An outreach talk on Nowruz (the Persian New Year) and the astronomy of calendars, explaining how lunar, solar, and lunisolar systems keep time and why the Persian calendar is tied to the spring equinox. It also covered the history and structure of the Iranian calendar and the cultural traditions of Nowruz, from its origins to modern celebrations.

Angular two-point correlation function of Euclid Early Data

Published: January 22, 2025

Presented measurements of the angular two-point correlation function using Euclid Early Data, focusing on methodology, early catalogue validation, and key systematic checks relevant to clustering analyses.

CRS BG and LRG target selection and angular clustering

Published: February 24, 2025

The Cosmology Redshift Survey (4MOST-CRS) will enable precision cosmological measurements using spectroscopic clustering of galaxies and quasars over 0.1 < z < 2.5 across >7000 deg^2. This talk presented the CRS Bright Galaxy and Luminous Red Galaxy target selections and angular clustering tests used to assess catalogue quality and uniformity.

Mapping the Universe: The Past, Present, and Future of Sky Surveys

Published: August 28, 2025

A public talk on how sky surveys evolved from early star catalogues to modern projects such as Gaia, 4MOST, DESI, LSST, and Euclid, and how these surveys help answer questions about galaxy growth, dark energy, and the cosmic web.
