"The figure of Galileo as the initiator of modern science has been one of the most debated throughout history, and not only for its role in the creation of...
Evidence for a black hole in the X‐ray transient XTE J1859+226
We present the results of time‐resolved optical photometry and spectroscopy of the X‐ray transient XTE J1859+226 (V406 Vul). Photometric observations taken...
Evidence for inflows and outflows in the nearby black hole transient Swift J1727.8-162
The transient Swift J1727.8-162 is the latest member of the X-ray binary black hole family to be discovered. They are formed by a black hole and a low-mass star...
Evidence of the impact of quasar driven outflows on recent star formation
We present the results of our spatially resolved investigation into the interplay between the ages of the stellar populations and the kinematics of the warm...
Exploring a new definition of the green valley and its implications
Galaxy formation remains one of the major open problems in astrophysics today. There is a wide range of mechanisms that control the transformation of gas into...
Extreme magnification of a distant star by a galaxy-cluster lens
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z ...
