Two postdoctoral positions in gravitational physics at the University of Mississippi

Saturday, February 27, 2021

The gravity group at the University of Mississippi invites applications for two postdoctoral researchers in gravitational physics and astrophysics. One postdoctoral position will focus on numerical relativity and tests of theories beyond GR, and will be supported by NSF–2047382. The second postdoctoral position will focus on gravitational-wave astrophysics and data-analysis. Each position is for two years, with potential for renewal for a third year contingent on performance and funding. A PhD in physics/mathematics/astronomy is required by the time of the initial appointment.

The successful applicants will also develop and advance independent research programs, collaborate with UMiss gravity group faculty (Leo Stein, Anuradha Gupta, and Luca Bombelli) on their research, and help to train UM students. UMiss is a member of the Simulating eXtreme Spacetimes (SXS) collaboration, and the LIGO Scientific Collaboration (LSC), the LISA consortium, and will thus provide ample opportunities to collaborate with other SXS, LSC, and LISA member institutions.

The nominal starting date for the positions is Sep. 1, 2021, but is flexible.

Applicants should submit an application by sending an email to <grpostdoc@phy.olemiss.edu>, including: a complete CV in PDF format (including publication list); a research proposal which covers research interests and experience; and contact information for three professional references who may provide letters. Please arrange for your references to also mail letters to this same address. Use the email subject “Gravity postdoc.”

Review of applications will begin Apr. 1, 2021 and will continue until the positions are filled.

Please direct questions about the positions to Anuradha Gupta <agupta1@olemiss.edu>, and Leo Stein <lcstein@olemiss.edu>.

The University of Mississippi is an EOE/AA/Minorities/Females/Vet/Disability/Sexual Orientation/Gender Identity/Title VI/Title VII/Title IX/504/ADA/ADEA employer.

Welcome to Anuradha Gupta, new faculty member

Tuesday, January 28, 2020

Dr. Anuradha Gupta has just joined us as an Assistant professor. She received her Ph.D. from the Tata Institute of Fundamental Research, Mumbai (India). Before coming to the Univ. of MS, she was a postdoctoral researcher with the Institute for Gravitation and the Cosmos at Pennsylvania State University. Dr. Gupta has broad interests in gravity and astrophysics, including: Gravitational wave source modeling, their detection and parameter estimation, dynamics of spinning and precessing binaries, binary formation channels, neutron star structure and tidal interactions, testing theories of gravity, numerical relativity, gravitational wave detector’s data and noise characterization. Please join us in giving her a warm welcome!

Postdoctoral research position in gravitational physics at the University of Mississippi

Monday, August 27, 2018

The gravity group at the University of Mississippi invites applications for a postdoctoral researcher in gravitational physics / astrophysics, with emphasis on: strong-field gravity, compact objects, gravitational waves, testing general relativity, numerical relativity, gravitational-wave data analysis, and related topics. A PhD in physics/mathematics/astronomy is required by the time of the initial appointment. Candidates should have expertise in analytical relativity and/or numerical computing, ideally both. The position is for two years, with potential for renewal for a third year contingent on performance and funding.

The successful applicant will develop and advance their own independent research program, collaborate with UM gravity group faculty (Luca Bombelli, Marco Cavaglia, and Leo Stein) on their research, and help to train UM students.

Applicants should submit an application by sending an email to <grpostdoc@phy.olemiss.edu>, including: a complete CV in PDF format (including publication list); a research proposal which covers research interests and experience; and contact information for three professional references who may provide letters. Letters are not requested at this time; these will be solicited later. Use the email subject “Gravity postdoc”.

Review of applications will begin Nov. 1, 2018 and will continue until the position is filled.

Please direct questions about the position to Leo Stein <lcstein@olemiss.edu>.

GRG Editor’s Choice: Extreme Gravity Tests with Gravitational Waves from Compact Binary Coalescences

Wednesday, April 4, 2018

The first part of our review article Extreme gravity tests with gravitational waves from compact binary coalescences was published today in General Relativity and Gravitation and selected as an Editor’s Choice.

This review is part of the Topical Collection Testing the Kerr spacetime with gravitational-wave and electromagnetic observations (Guest Editor: Emanuele Berti).

New PRL: Spontaneous Scalarization for Black Holes and Neutron Stars in Scalar-Gauss-Bonnet Gravity

Friday, March 30, 2018

In a new paper published today in Physical Review Letters we identify a class of modified theories of gravity where gravity is mediated by a scalar field coupled to quadratic terms in the curvature (the so-called “Gauss-Bonnet invariant”) that could be particularly interesting in the context of testing general relativity with gravitational wave detectors. These theories exhibit the phenomenon called “spontaneous scalarization” for both black holes and compact stars: for certain classes of solutions the scalar field can “grow” and modify the structure of these compact objects, with possible observational signatures. These theories formally admit all of the stationary solutions of general relativity, but the general relativistic solutions are not dynamically preferred if certain conditions are satisfied. Remarkably, black holes exhibit scalarization if their mass lies within one of many narrow bands. Two related papers (one by Antoniou et al., the other by Doneva and Yazadjiev) appeared in the same issue of Physical Review Letters.
