Astronomy, Physics, and Statistics Institute of Sciences (APSIS)

!!! NEW !!!   The GW APSIS team  is delighted to announce the establishment of the Michael W. Thacher Visiting Professor Grant, extending over a three-year span (2017-2020). The grant is providing travel expenses annually for two guests of the Astrophysics Group in APSIS, to visit for a week to work with the group, either on ongoing collaborations or on new projects. Visiting scientists will be selected from a suggested pool by the group members; we are also open to external suggestions for visitors, provided that funds are still available.

The GW Astronomy, Physics, and Statistics Institute of Sciences (APSIS) is a multi-disciplinary institute focused on multi-wavelength observations, statistical inference, modeling, and simulations of high-energy phenomena in the Universe. APSIS was chartered at the end of 2015, and comprises groups from the GW Physics, Statistics, and Mathematics Departments. Professors Chryssa Kouveliotou (Physics) and Tatiyana Apanasovich (Statistics) serve as the Director and Deputy Director, respectively. The primary objective is to establish a collaborative learning and research environment stemming from multi-disciplinary interests of - initially - the physics, astrophysics and statistics faculties, and their graduate and undergraduate students, involved in data-intensive research and applications.

The unifying theme and focus of APSIS is the multifaceted investigation of the properties and manifestations of matter under extreme conditions of pressure, temperature, density, and magnetic fields through multi-wavelength observations, modeling, and simulations that probe spatial, spectral, and time domains. The APSIS members are actively engaged in observations of astronomical sources using the world’s best space- and ground-based facilities. The combination of two Physics Department groups brings together expertise in traditional multi-wavelength astronomy and emerging subfields in astrophysics with particle physics, while colleagues in the Statistics and the Mathematics Departments add expertise in analytical, numerical, and statistical techniques especially pertinent to Big Data science. The APSIS goal in the next five years is to become a truly GW-wide initiative by providing a data science training and research facilities to researchers and professionals who recognize the potential of Big Data but do not have the tools to explore it. APSIS will address issues of big data storage, transport, and retrieval, a very current and real problem, given the large number of new telescopes coming up with huge amounts of data production. APSIS will also engage with industry partners as sponsors of research projects using their Big Data to train graduate students through internships at their institutions.
