Cosmology and extragalactic astronomy are fields that explore the universe's structure, origin, and evolution, focusing on phenomena beyond our galaxy. Recent research in these areas has made ...

This course provides an overview of extragalactic astronomy with an emphasis on the development of large-scale structures and galaxy formation. The first part of the course deals with the development ...

Abstract: Establishing the reliability with which stellar population parameters can be measured is vital to extragalactic astronomy. Galactic globular clusters (GCs) provide an excellent medium in ...

Feb. 6, 2025 — Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these ...

It’s the most energetic particle of its kind ever discovered, and scientists have no idea where it came from. By Katrina Miller NASA and European scientists explain how they calculate the ...

Using the X-ray Polarimetry Explorer (IXPE) and Neutron star Interior Composition Explorer (NICER), Indian astronomers have observed an X-ray binary system known as GX 9+1. Results of the ...

For the first time, astronomers have succeeded in observing the magnetic field around a young star where planets are thought to be forming. The team was able to use dust to measure the three ...

The accurate modelling of the point spread function (PSF) is of paramount importance in astronomical observations, as it allows for the correction of distortions and blurring caused by the telescope ...

CAPE CANAVERAL, Fla. — Europe’s Euclid space telescope has detected a rare halo of bright light around a nearby galaxy, astronomers reported Monday. The halo, known as an Einstein ring ...

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space ...

Our Centre for Extragalactic Astronomy led a global effort — including 45 international partners — to discover 44 new stars while studying the distant Dragon Arc galaxy. And they are collaborating on ...

It is significant for revealing the formation mechanism of the lunar Mascon to invert the refined 3-D lunar crust and upper mantle structure of the Mare Serenitatis. As the development of space ...
