CSENV  Popular
CSENV (pronounced See-Senv) is a code that computes the chemical abundances for a desired set of species as a function of radius in a stationary, non-clumpy, CircumStellar ENVelope. The chemical species can be atoms, molecules, ions, radicals, molecular ions, and/or their specific quantum states.

CAOS (Code for Adaptive Optics Systems)  Popular
The CAOS system (where CAOS stands for Code for Adaptive Optics Systems), completely IDL-based, is composed of a graphical programming environment (the CAOS Application Builder) which can load different packages (set of modules). Current publicly distributed packages are the Software Package CAOS (the original adaptive optics package), the Software Package AIRY (an image-reconstruction-oriented package - AIRY stands for Astronomical Image Restoration with interferometrY), the Software Package PAOLAC (a simple CAOS interface for the analytic IDL code PAOLA developped by Laurent Jolissaint - PAOLAC stands for PAOLA within Caos), and a couple of private packages (not publicly distributed but restricted to the corresponding consortia): SPHERE (especially developped for the VLT planet finder SPHERE), and AIRY-LN (a specialized version of AIRY for the LBT instrument LINC-NIRVANA).

cloudy  Popular
Cloudy is designed to simulate emission line regions ranging from the intergalactic medium to the Broad Line regions of Quasars. It can be used to predict either the structure or the observed spectrum from such regions.

cmbfast  Popular
This is the most extensively used code for computing cosmic microwave background anisotropy, polarization and matter power spectra. The code has been tested over a wide range of cosmological parameters. We are continuously testing and updating the code based on suggestions from the cosmological community.

DDSCAT  Popular
DDSCAT, a Fortran code for calculating scattering and absorption of light by irregular particles, has been jointly developed by Bruce T. Draine (Dept. of Astrophysical Sciences, Princeton University) and Piotr J. Flatau (Scripps Institution, UCSD); the current version is DDSCAT.5a10 .

DUSTY  Popular
The code DUSTY was developed at the University of Kentucky by Zeljko Ivezic, Maia Nenkova and Moshe Elitzur for a commonly encountered astrophysical problem: radiation from some source (star, galactic nucleus, etc.) viewed after processing by a dusty region. The original radiation is scattered, absorbed and reemitted by the dust, and the emerging processed spectrum often provides the only available information about the embedded object. DUSTY can handle both planar and centrally-heated spherical density distributions.

FASTELL  Popular
FASTELL is a code to calculate quickly and accurately the lensing deflection and magnification matrix for the SPEMD lens galaxy model. The SPEMD consists of a softened power-law radial distribution with elliptical isodensity contours.

Flash  Popular
FLASH is a modular, adaptive-mesh, parallel simulation code capable of handling general compressible flow problems found in many astrophysical environments. FLASH is designed to allow users to configure initial and boundary conditions, change algorithms, and add new physics modules with minimal effort. It uses the PARAMESH library to manage a block-structured adaptive grid, placing resolution elements only where they are needed most. FLASH is being developed by the Center for Astrophysical Thermonuclear Flashes, or Flash Center, at the University of Chicago.
