The Deadly Spider Has Been Found!

A few days ago (Feb. 5th) I wrote a post about a special source, named XSS J12270-4859, a cryptic name behind a binary system composed of a neutron star and a normal companion star slightly less massive than our Sun.

A Deadly Spider in Disguise

My colleagues and I have recently studied a new peculiar binary system (XSS J12270-4859) formed by a neutron star and a low mass star that can be found in the constellation Centaurus, in the southern hemisphere. Our recent work, lead… Continue Reading →

The Missing Link

(Update: one paper is now published http://iopscience.iop.org/2041-8205/781/1/L3/) Today I’d like to  tell a brief story and discuss three recent papers accepted or submitted to The Astrophysical Journal & The Astrophysical Journal Letters (and make some self-promotion as I’ve been involved… Continue Reading →

Is There Anybody Out There?

How many times have we heard the question “are we alone in the Universe”? Does life exist somewhere else? Does intelligent life exist? There’s no need to introduce the topic, as countless discussions have been made through the centuries. Still,… Continue Reading →

Quantum Vortices in the Sky

Turbulence is a common chaotic phenomenon that everyone has certainly experienced: you witness the development of turbulence when you stir a coffee too vigorously or watch the smoke of a cigarette or feel the aeroplane going up and down. What… Continue Reading →

A New Millisecond Pulsar Catalogue

Triggered by the idea of J. Hessel while I was working at ASTRON, I decided to create a new pulsar catalog that includes all radio, gamma, and accreting millisecond pulsars known. The list is updated but of course omissions and… Continue Reading →

Some Free Codes for Top Research in Astronomy

I am mostly an observer working in the field of high energy astrophysics, doing experiments and performing observations with space and ground-based telescopes. However, once in a while I also like very much to use numerical codes to solve complex… Continue Reading →

The Mutant Star

Accreting Millisecond X-Ray Pulsars are amazing objects (see also my research page in the section “Accreting Millisecond X-ray pulsars”). They are neutron stars that orbit around a relatively small star like our Sun or less massive and eat gas from… Continue Reading →

The Clouds Around the Monster

Neutron stars are few kilometres sized objects that come to life when a massive star dies in a devastating supernova explosion. A few months ago a very peculiar neutron star has been discovered in an even more peculiar location of… Continue Reading →
