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…

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.



2019 Highlights

Crashing Galaxies Drive Huge Shockwaves into Deep Space

Research conducted by an international team of astronomers, published in the scientific journal Nature, revealed an enormous nebula around an extreme form of a merging galaxy.

The galaxy named Makani (Hawaiian for 'wind') is pushing a…

Modeling the evolution of a binary system leading to a Neutron Star collision

As a star evolves, depleting the hydrogen in its nucleus and becoming a supergiant, its size may increase by more than 500 times. If the star is in a binary system it enters the so-called common envelope phase, in which the evolved star engulfs…

Inclination effects on the X-ray emission of Galactic black-hole binaries

Galactic black-hole X-ray binaries (BHBs) emit a compact, optically thick, mildly relativistic radio jet when they are in hard and hard-intermediate states. In these states, BHBs exhibit a correlation between the time…
