The recent detection of a cosmic explosion by the Einstein Probe is stirring excitement among space watchers everywhere.

"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead ...

An official statement issued on Wednesday said that this length compares to roughly 10 times the size of the Milky Way’s ...

Einstein Probe's Wide-field X-ray Telescope (WXT) detected a burst of low-energy X-rays. Astronomers call such X-rays "soft," ...

a hypothesis known as the 'tired light' theory suggested that light loses energy during its long cosmic journeys, leading to the redshift. However, as it failed to explain numerous observations ...

Drawing upon data from Vesto Slipher and Henrietta Leavitt, Hubble demonstrated a correlation between galactic distance and redshift. ... We now know this is due to cosmic expansion. Space itself ...

As the light was shifted towards the red end of the spectrum (lower frequency/longer wavelength) this phenomenon was termed 'redshift'. Figure caption, Lower diagram shows spectrum of light ...

I work on theories of galaxy formation, reionization, first stars, primordial metal production, and numerical hydrodynamical simulations of high-redshift galaxies and the multi-phase intergalactic ...
