Chemical Elements as Tracers of the Evolution of the Cosmos

GAA - Astronomy and Astrophysics Group, UPC Barcelona

The Astronomy and Astrophysics Group at UPC Barcelona

The Astronomy and Astrophysics Group (GAA) gathers researchers from the Department of Physics of the Technical University of Catalonia (UPC) since 1995. Currently, the GAA consists of 5 faculty members, 1 Ramon y Cajal fellow (tenure-track position), and 7 PhD students. 

The research interests of the GAA comprise a wide spectrum of areas in Astronomy & Astrophysics, mostly in stellar structure and evolution. The main research interests of the group are:

* Astrophysics

  Stellar Structure and Evolution

  • AGB and Super-AGB Stars
  • Physics of White Dwarfs: Cooling, Populations; Surveys
  • Compact Binaries and Stellar Explosions: Type Ia supernovae; Supernova Progenitors; Classical and Recurrent Novae; Neutron Star and Black Hole X-Ray Binaries; X-Ray Bursts
  • Stellar Mergers
  • Physics of Neutron Stars: Mass and Radius Constraints

   Galactic Astrophysics

  • Galactic Evolution: Age, Star Formation History, Minor Mergers
  • Galactic Components
  • Kinematics

* Techniques

    Computational Astrophysics: Spherically Symmetric and Multidimensional Modeling; MHD

    Nuclear Astrophysics: Nucleosynthesis. Sensitivity Studies. Nuclear Reactions

    Laboratory Astrophysics: Plasma Physics

* Observations and Space Missions

    High-energy (X- and γ-rays) and optical observations

    Space Missions: Ground Segment and Payload

In the period 2000 – 2017, the GAA members have published 345 refereed papers, 7 invited review papers, 1 book, 5 book chapters and 244 non-refereed publications, and has advised (or co-advised) 22 PhD Theses in these topics.

 The GAA is currently located in two campuses: the Campus Diagonal-Besòs (Barcelona) and the Campus Castelldefels  (Castelldefels, 15 km south of Barcelona).
