Revealing the hidden nuclei of galaxies with JWST

The James Webb Space Telescope (JWST) is the largest infrared telescope facility ever sent to space, and is poised to provide a tremendous…

Black hole jet reveals its secrets!

Blazars are some of the brightest objects in the sky. They consist of a…

Pulsation vs Rotation in Be/X-ray binaries

We think of stars as stable systems and indeed they take millions of years to evolve significantly. However, stable does not mean static. Many stars, from all masses and sizes display pulsations on timescales between…

A new pathway for SNe-Ia explosions

It is known that low-mass stars end their lives as white dwarfs, while high-mass stars become…

The accretion disc size "problem" in Active Galaxies

Active Galactic Nuclei (AGN) are the most powerful, persistent objects in the Universe. They emit enormous amount of…

Detection of a Strong Candidate Signal for the Stochastic Gravitational Wave Background at NHz Frequencies

The European Pulsar Timing Array (EPTA) is a scientific collaboration bringing together teams of astronomers around the largest European radio…

The Turbulent Assembly of Hot DOGs

Super-massive black holes (SMBHs), that is black holes with at least one million times the mass of the Sun, are…

Modelling the UV/optical continuum time-lags in AGN

A group of astronomers, including Prof. Iossif Papadakis of the Institute of Astrophysics and the Department of Physics of the University of Crete  have recently…

Hunting for the signature of the first moments of the Universe just got more complicated

Polarized light emitted by Galactic interstellar dust acts as a veil obscuring our view of microwave emission from the early Universe - the cosmic microwave background (CMB), often called the Big Bang "ashes". An…

The source of hard X-rays in black hole binaries

The models that seek to explain the reflection spectrum in black hole binaries usually invoke a point-like primary source of hard…

2020 Highlights

A new probe of Dark Energy

Large scale structures, such as groups of galaxies, galaxy clusters, and superclusters, have long been the workhorses of observational cosmology. Now a new way to observe them promises to provide new insights to one of…

Understanding The Physics Of U/LIRGs With Spitzer

Luminous and ultraluminous infrared galaxies (LIRGs/ULIRGs) have been an active area of galaxy research since their discovery more than three decades ago. With its vast increase in sensitivity in the infrared, Spitzer…

New Icy Planet Detected In Our Nearest Exoplanetary System

Strong indications for the existence of a second planet in orbit around Proxima Centauri, the nearest star to the Sun, have been recently unveiled by an international team of scientists.
