The department of Astrophysics, Cosmology and Fundamental Interactions (COSMO) is a newly-formed department in CBPF. COSMO is an active department of 10 faculty members, holding weekly seminars, weekly journal clubs in various areas, organizing regular conferences and workshops, supervising many postgraduate students and postdoctoral researchers, attracting a dynamic flow of national and international visitors, establishing collaborations with international research groups and institutions as well as lecturing advanced post-graduate courses. The research carried out in COSMO comprises (but is not limited to) the following areas:
* Quantum Cosmology: bouncing models; primordial cosmology; theory of cosmological perturbations of quantum-mechanical origin and their imprints on the Cosmic Microwave Background radiation and large-scale structure. [Felipe Tovar, Nelson Pinto-Neto]
* Out-of-equilibrium Relativistic Thermodynamics and Non-linear Electrodynamics: applications to cosmology; self-gravitating systems without singularity and to gravitational collapse.
* Gravitational Waves: black hole inspirals in the extreme mass-ratio limit; gravitational self-force; ringdown. [Marc Casals]
* Spectroscopy of Black Holes: quasinormal modes; classical stability in four and higher-dimensions; Green function. [Marc Casals]
* Quantum Black Holes: evaporation via Hawking radiation; black hole thermodynamics; information paradox; 'gauge-gravity' duality. [Marc Casals]
* Gravitational Lensing: simulations and inverse modelling of gravitational arcs; arc identification and characterisation; weak lensing and galaxy clusters. [Martin Makler]
* Astronomical Image Processing and Wide-field Surveys: object detection; modelling of the point-spread-function; galaxy structural parameters; quality assessment. [Martin Makler]
* Dark Matter and Dark Energy: observational constraints from lensing; large-scale structure; Cosmic Microwave Background; galaxy clusters and supernovae; models and observational tests of dark matter and dark energy unification; heterogeneous cosmological models as alternatives to dark energy.
* Analogue Models of Gravity and Effective Geometry: non-linear electrodynamics; non-linear scalar field theories; analogue black holes.
* Solutions of Heun Equations and their Applications: generalized spheroidal wave equation; Schrödinger equation and linear perturbations of space-times. [Bartolomeu Figueiredo]
