A quiet revolution is unfolding in the study of distant galaxies, one that lets astronomers pinpoint individual stars across the vast gulfs of time and space. Using the James Webb Space Telescope (JWST), a team of researchers has identified over 40 individual stars in a single galaxy located halfway across the observable universe. These stars […]

In the vast expanse of the universe, galaxies are not isolated islands but are interconnected through a vast network known as the “cosmic web.” This intricate structure, composed of dark matter and gas, forms the backbone of the cosmos, guiding the formation and evolution of galaxies. Recent advancements have allowed astronomers to capture a high-definition […]

The evolution of the cosmic star formation rate density paints a dynamic picture of galaxy evolution, with rapid stellar build-up at redshifts above 2, followed by a stark drop in SFRs of galaxies towards the present day. The origins of this down-turn are likely due to a mixture of feedback processes, broadly categorized as caused […]

Stellar population synthesis (SPS) is the prevailing framework for predicting the spectral energy distribution of a galaxy (SED) from its fundamental physical properties. SPS is a mature subfield with a long history dating back to the seventies of the last century. Applications of SPS range from inferring the physical properties of individual galaxies, to forward […]
