Astrophysics is a hybrid of Physics and Astronomy that attempts to explain the physical workings of the celestial objects or phenomenons. Astrophysics has two subdivisions: theoretical, and applied or experimental.

Research focus
Research in astrophysics addresses a great variety of topics, for example:
Stars
- - stellar evolution
- - magnetic field properties
- - stellar convection
Stellar atmospheres
- - nature of spectral analysis
- - electron density
The Galaxy (the Milky Way)
- - interstellar gas and dust
Galaxies
- - modeling the environs of galactic-centre massive black holes;
- - the structure and dynamics of galactic bars;
- - the flow of gas into and out of galaxies;
- - the role of active galactic nuclei in limiting the growth of galaxies.
CMB (cosmic microwave background radiation)
Astroparticles
Black holes
Dark matter
Dark energy
Dark energy is a theoretical energy which exerts a negative attraction or opposes the positive attraction of matter and causes the universe to expand.[1][2]
Astrochemistry
Astrochemistry involves the study of the role of the chemical bond and organic chemistry in nature on a cosmic scale.
- Over 140 molecules have been identified in the interstellar gas and circumstellar shells. To date the largest is a carbon chain with 13 atoms and a molecular weight of 147.
