Physics of Neutron Stars

This will be the 10th gathering on neutron star physics in Saint Petersburg (after those in 1988, 1992, 1995, 1997, 1999, 2001, 2005, 2008, and 2011). In 2014 the conference will commemorate the 100th birthday of Yakov Borisovich Zel’dovich (1914—1987), the famous Soviet physicist and astrophysicist. The conference will cover all major topics of observations and theory of neutron stars, including rotation powered pulsars, pulsar emission mechanisms, pulsar wind nebulae, magnetars, isolated cooling neutron stars, central compact objects, accreting X-ray pulsars (particularly, millisecond pulsars), neutron stars in low-mass X-ray binaries, X-ray bursts, equation of state, structure and evolution of neutron stars, mechanisms of supernova explosions and neutron star mergers.

Extreme-Astrophysics in an Ever-Changing Universe

Since ancient times, astronomers’ attention has been drawn to changes in the sky. Today we know that most phenomena observed in “time-domain” astronomy are related to extreme astrophysical events or processes. Whether it is the explosion of stars in supernovae or the observations of flare stars, pulsars, gamma-ray bursts, blazars or active galactic nuclei, time-domain astronomy stretches across the whole electromagnetic spectrum and beyond. With increasing technical capabilities, the 21st century will see corresponding new instruments being developed or coming online, revolutionising our view of the ever-changing Universe.

The X-ray Universe

The XMM-Newton Science Operations Centre is organising a major astrophysical symposium from Monday 16th to Thursday 19th of June 2014 in Dublin, Ireland. The symposium is the fourth international meeting in the series “The X-ray Universe”. The intention is to gather a general collection of research in high energy astrophysics. The symposium will provide a showcase for results, discoveries and expectations from current and future X-ray missions. Continua a leggere The X-ray Universe

27° Texas Symposium on Relativistic Astrophysics

The 27th Texas Symposium on Relativistic Astrophysics will be held in downtown Dallas December 8 – 13, 2013.

Hot Topics in General Relativity and Gravitation

This international conference will be held as part of the framework of the Recontres du Vietnam. Our aims are to discuss and review recent developments on:

  • Astrophysics of compact objects
  • Gravitational waves (experimental and theoretical)
  • Experimental gravity and tests of General Relativity
  • Alternative gravity theories and Cosmology related issues

The conference will consist of plenary sessions for indepth oral presentations (review talks and talks on specific specialised topics), parrallel and poster sessions (contributions sollicitated or selected from abstract submission). Special emphasis is being placed on active participation by young researchers and post-docs. A common plenary session with the conference Cosmology in the Planck Era is planned.

Spectral/timing properties of accreting objects: from X-ray binaries to AGN

“Spectral/timing properties of accreting objects: from X-ray binaries to AGN” is a 3-day workshop to be held at the European Space Astronomy Centre (ESAC) in April 2013. The aim of the workshop is to review the current understanding of the physics of accretion onto compact objects across the full range of masses, by bringing together young and active experts of the field. In order to encourage discussions and maximize collaborations, the attendance to the workshop will be limited to about 70 people, that will be selected on the basis of the proposed contribution after the registration deadline. There will be no registration fee.

The main scientific topics covered will be:

– Accretion modes at different scales;

– States and state transitions;

– Inflow/outflow connections;

– Accretion/ejection mechanisms;

– Unification schemes.
