Vincent Tatischeff (CSNSM, CNRS)17/12/2015, 14:24Talke-ASTROGAM is a gamma-ray observatory to be proposed as a Medium-size mission for the ESA science program. It is dedicated to the observation of the Universe with unprecedented sensitivity in the energy range 0.3 – 100 MeV extending up to GeV energies, together with a ground-breaking polarization capability. In this energy window, a variety of phenomena and sources await their discovery and...Go to contribution page

Prof. J S Yadav (Tata Institute of Fundamental Reaserch)17/12/2015, 14:43TalkASTROSAT is India's first science satellite dedicated to multiwavelength astronomy. It has five science payloads which will cover UV to hard X-ray in low earth orbit. LAXPC instrument is one of the major instruments (415 kg payload weight and above 100 electronic cards). This instrument is designed and developed at TIFR and all the three LAXPC flight units have successfully completed...Go to contribution page

Dr Paolo Soffitta (IAPS/INAF)17/12/2015, 15:06TalkXIPE, the X-ray Imaging Polarimetry Explorer, is one of the three missions selected by ESA for study phase for down-selection of the fourth medium size mission. XIPE will measure the polarization in hundreds of celestial sources of different classes. It will allow for answering, in a novel way, to questions related to the acceleration phenomena in PWNe, Supernovae and blazars, to the transport...Go to contribution page

Dr Jan-Willem den Herder (SRON)17/12/2015, 15:25TalkThe Athena mission is the second large mission of ESA with an expected launch date of 2028. The data will be gathered by a very large mirror (2 m2) with a 5 arcsec resolution. Athena will have two instruments: the Wide Field Imager combines a large field of view (40 x 40 arcmin2) with Si-class energy resolution and the X-ray Integral Field Unit (X-IFU) which enables high spectral resolution...Go to contribution page

Stefan Gillessen (Max Planck Inst fur Extraterrestrische Physik)17/12/2015, 16:15TalkLocated at 8kpc only, the Galactic Center allows studying a galactic nucleus in unparalleled detail. With the advent of high-resolution, near-infrared instrumentation in the last decade it became possible to follow individual stellar orbits around the radio source Sgr A* with orbital periods as short as 12 years. The orbits determine the mass of Sgr A* to 4 million solar masses, and thus...Go to contribution page

Prof. Sergei Klioner (Lohrmann Observatorium, Technische Universitaet Dresden)17/12/2015, 16:35TalkEsa's second space astrometry mission Gaia was launched in December 2013 and after an extended commissioning period started its scientific operations in July 2014. After 17 months of observations Gaia delivered an immense dataset of high-accuracy positional observations. In spite of some unexpected difficulties with the instrument, Gaia Data Processing and Analysis Consortium is progressing...Go to contribution page

Robert Laing (ESO)17/12/2015, 16:55TalkThe Atacama Large Millimetre/Sub-millimetre Array, ALMA, is the leading instrument for observations in the frequency range from 35 to 950 GHz. It is an aperture-synthesis array consisting of 66 antennas of 12 and 7m diameter equipped with sensitive receivers located at 5000m altitude on the Chajnantor Plateau in Northern Chile. ALMA is just entering its third observing cycle and is producing...Go to contribution page

Dr Robert Braun (SKA Organisation, Jodrell Bank Observatory)17/12/2015, 17:15TalkThe SKA is now in the detailed design phase with construction scheduled to begin in early 2018, followed by early science from about 2020. A major component of its broad-ranging science program is focused on addressing questions in fundamental physics. The current status of the project will be summarised and the prospects for advancing relativistic astrophysics will be highlighted.Go to contribution page

Dr Kuo Liu (Max-Planck-Institute for Radio Astronomy)17/12/2015, 17:35TalkSearching for gravitational waves has nowadays been a vital astrophysical experiment in gravity and pulsar timing array (PTA) constitutes the major effort in low frequency regime. The detection of gravitational waves with PTAs relies on the technique of high precision pulsar timing currently achieved with the 100-m class radio telescopes. In this talk, I will present an overview of the Large...Go to contribution page

Joel Berge (ONERA)17/12/2015, 17:55TalkMICROSCOPE is a French Space Agency scheduled for launch in 2016, that aims to test the Weak Equivalence Principle in space: one century after the publication of Einstein’s General Relativity, it could allow us to reveal a breach in the theory. Thanks to its cutting-edge-technology inertial sensors, it will allow us to measure the Eotvos parameter down to $10^{-15}$, two orders of magnitude...Go to contribution page

259. The High Energy cosmic-Radiation Detection (HERD) Facility onboard China's Future Space StationMing Xu (Chinese Academy of Sciences (CN))17/12/2015, 18:15PosterThe High Energy cosmic-Radiation Detection (HERD) facility is one of several space astronomy payloads onboard China's future Space Station, which is planned for operation starting around 2020. It is designed as a next generation space facility focused on indirect dark matter search, precise cosmic ray spectrum and composition measurements up to the knee energy, and high energy gamma-ray...Go to contribution page

Dragan Hajdukovic (Institute of Physics, Astrophysics and Cosmology (ME))17/12/2015, 18:25PosterThe unrivalled advantage of tiny trans-Neptunian binaries is that they are the best available realisation of an isolated two body system with very weak external and internal Newtonian gravitational field. As a consequence, in many cases (as for instance in the case of the binary (55637) 2002 UX25), the known Newtonian precession of orbit of the satellite is so small that cannot be detected by...Go to contribution page

Mariusz Dabrowski (University of Szczecin)17/12/2015, 18:35PosterIn this talk I will briefly present the advantages and drawbacks of varying speed of light c cosmologies and relate them to the of varying fine structure constant α theories. Then, I will discuss some new tests (redshift drift and angular diameter distance maximum against Hubble function) which may allow measuring timely and possibly even spatial change of the speed of light. The criteria to...Go to contribution page
