Understanding black holes: young star clusters filling up gaps
Since their groundbreaking discovery of gravitational waves from a pair of in-spiralling black holes back in 2015, the LIGO-Virgo-KAGRA collaboration has detected nearly 70 candidates of such events, 50 being confirmed and published until now. A tight binary comprising black holes or neutron stars would always spiral in and become tighter with time by losing energy in the form of gravitational waves until they plunge onto each other and merge.
Modifying gravity to save cosmology
The unexpectedly rapid local expansion of the Universe could be due to us residing in a large void. However, a void wide and deep enough to explain this discrepancy—often called the “Hubble tension”—is not possible in standard cosmology, which is built on Einstein’s theory of gravity, General Relativity. Now, a team of astronomers have shown how such a void is possible in one of the leading alternative gravity theories called Modified Newtonian Dynamics (or MOND).
Supermassive black holes: monsters in the early Universe
A star such as the Sun will never leave a black hole because the quantum forces between matter stop this from squeezing into a sufficiently small volume. Once the Sun dies it will merely leave a white dwarf star, which slowly cools and dims over billions of years. But when the nuclear furnace of a star weighing more than approximately 20 times the Sun exhausts itself, the quantum forces cannot halt its immense gravitational collapse, sparking its explosion as a supernova and often leaving a stellar mass black hole in memory of its previous glory.
The enduring mystery of how galaxies grow up
Astronomers have discovered that there are two different types of galaxies in the Universe: elliptical galaxies and spiral galaxies. Elliptical galaxies are dead galaxies full of very old, red stars that move on chaotic random orbits around the centre of their galaxy in such a way that makes their shape look like fluffy footballs. On the other hand, live spiral galaxies contain both old stars and many new, freshly formed stars. They appear as beautiful spiral galaxies as their stars and gas move on nearly circular paths around a common centre in a thin rotating disk
