Giannios Group

- High Energy Astrophysics


September 2017: Adithan, Rodolfo and Dimitrios propose a promising source a light in connection to gravitation wave detections of binary neutron star mergers. 

September 2017: Maria and Dimitrios are organizing a special session about "Jets in the era of multi-messenger astronomy" to be held in the EWASS 2018 conference.  Abstract submission is open until 27 November 2017. See also Maria's News & Views piece on Nature Astronomy about GRB polarization

August 2017: Our comprehensive study on the stability of relativistic jets appears to the Purdue Research highlights and receives extensive publicity: herehere, and here

June 2017: Maria, Rodolfo and Dimitrios propose a model that can, for the first time, explain the durations and luminosities of gamma-ray bursts.

June 2017: Dimitrios co-authors a detailed exploration on whether millisecond magnetars are the engines of gamma-ray bursts. 

April 2017: The students advance. Ian's work on the radio emission in the Galactic center and Adithan's work on the fallback rate of gas after a stellar tidal disruption have just been published.

March 2017: Great career advancement for the group's postdocs. Maria has been awarded the prestigious Lyman Spitzer, Jr. Postdoctoral Fellowship at Princeton University. Rodolfo has just accepted a tenure-track position at the Department of Physics and Astronomy at California State University Sacramento. Both positions start this Fall.

March 2017: Work from ian, Maria, and Dimitrios Highlighted by Nature Astronomy.

January 2017: Opening of a postdoctoral position in Giannios' group. To appear formally in next month's AAS job register. Applications accepted ASAP.


December 2016: Dimitrios is awarded a 3-year, NASA Astrophysics Theory Program grant to study the emission from blazar jets. Maria is a co-investigator to this grant.

December 2016: Rodolfo, Dimitrios together with Alexander Tchekhovskoy completed a comprehensive study on the stability a relativistic jets.   

December 2016: Dimitrios and David Kaplan are awarded a Research Corporation grant aiming at "Identifying the origin of the Extreme Scattering Events". It is the second time that Dimtirios receives such a competitive award from the Research Corporation. 

October 2016: The group members travel and present their research. Maria presents at Goddard, Harvard, Columbia; Ian at Columbia; Adithan and Rodolfo at Huntsville; Dimitrios to Tuscon.

September 2016: Maria gives an invited talk at a Cern workshop, Dimitrios gives invited presentations in Bonn and Paris.

August 2016: Maria, Dimitrios publish with George Vasilopoulos a study on the origin of the TeV emission from the enigmatic blazar Ap Librae. 

July 2016: Dimitrios involved in record-breaking precision measurement tracking the aftermath of a of a star being swallowed by a supemassive black hole. See also here and here.

June 2016: Maria, Dimitrios publish a comprehensive paper on the origin of the emitting regions in jets from supermassive black holes.

May 2016: Our undergrad Joe Whitehead published his first paper. Good work Joe, Rodolfo!

May 2016: Great presence of the group at the Purdue workshop on Plasma Astrophysics! Maria, Rodolfo and Ian give oral presentations.

April 2016: Adithan’s first paper accepted for publication. Way to Go, Adithan, Rodolfo!

March 2016: Ian’s first paper accepted for publication. Way to go, Ian, Maria!

February 2016: Maria is awarded the prestigious MERAC prize by the European Space Agency for the “best Thesis in Theoretical Astrophysics”. Congratulations, Maria!

January 2016: Dimitrios is asking “Is there new class of X-ray transients in the Galactic center?
