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.

[edit intro]

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.
