Frontiers in Radio Astronomy

Echoing the first FRA meeting in 2012, we are excited to announce the second international science symposium “Frontiers in Radio Astronomy” to be held in Guiyang, China between July 29th and 31st, 2015.  This meeting will focus on most recent development in radio astronomy and to explore the promises of FAST early science operation. It is hosted by National Astronomical Observatories of China and Guizhou Normal University, with  support from the Chinese Academy of Sciences, National Natural Science Foundation of China, and the Ministry of Science and Technology of China.

50° Rencontres de Moriond on Gravitation 100 years after GR

The Rencontres de Moriond and GRAM Colloquium on Gravitation will review the subject 4 years after the last edition. Continua a leggere 50° Rencontres de Moriond on Gravitation 100 years after GR

Testing Gravity

A three day workshop on various ways of testing gravity (cosmological, astrophysical and terrestrial). This is a topical theme, in part because of the growing interest in modified gravity theories motivated by the unexplained nature of dark matter and dark energy, and in part by improving technologies that open opportunities for new types of tests.

5° International Fermi Symposium

The two Fermi instruments have been surveying the high-energy sky since August 2008. The Large Area Telescope (LAT) has discovered more than a thousand new sources and many new source classes, bringing the importance of gamma-ray astrophysics to an ever-broadening community.

The 10° INTEGRAL Workshop “A Synergistic View of the High Energy Sky”

The goal of this workshop is to present and discuss (via invited and contributed talks and posters) the latest results obtained in the field of high-energy astrophysics using the International Gamma-Ray Astrophysics Laboratory INTEGRAL, and place these results in the context of other operational space-based missions, such as Swift, Fermi, AGILE, NuSTAR, and Maxi as well as ground-based VHE observatories. Correlative studies in lower energy bands, as well as neutrino- and gravitational wave observations are included as relevant for various source classes.

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.

What powers Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters?

Anomalous X-ray Pulsars (AXPs) and Soft Gamma-ray Repeaters (SGRs) are young, isolated neutron stars, which emit bright bursts of hard X-rays and, more rarely, exceptionally energetic giant flares. They are believed to have strong external magnetic fields of the order of 1014 – 1015G, reaching even higher values in their interior, and are known as magnetars. In this picture, both the steady-state X-ray flux and the emission of bursts/flares are thought to be powered by the reservoir of magnetic energy stored in the star’s interior.  Continua a leggere What powers Anomalous X-ray Pulsars and Soft Gamma-ray Repeaters?

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

Advancing Astrophysics with the Square Kilometre Array

In 2014 it will be 10 years since the publication of the comprehensive ‘Science with the Square Kilometre Array’ book and 15 years since the first such volume appeared in 1999. In that time numerous and unexpected advances have been made in the fields of astronomy and physics relevant to the capabilities of the Square Kilometre Array (SKA). The SKA itself has also progressed from an idea to a developing reality with a baselined Phase 1 design (request-for-proposals) and construction planned from 2017.  Continua a leggere Advancing Astrophysics with the Square Kilometre Array
