NUMÉRICO
Modificación de Códigos Cosmológicos
Numéricos
Coordinador: Luis Ureña (lurena@fisica.ugto.mx)
Main objective: Our aim is the
understanding and modification of the computational tools used
in the study of the observational data collected from the Cosmic
Microwave Background (CMB). Alternative models of dark matter
and dark energy will be introduced into the available software,
and their signature in the final output will be compared to the
observational data. This will allow us to restrict the parameter
space of the different proposals. In the same line, we will work
on the making of pedagogical packages and notes to be included
in advanced Cosmology courses in our country.
Propósito: Estudio y modificación
de las herramientas computacionales disponibles para el análisis
de los datos experimentales obtenidos de la Radiación del
Fondo Cósmico (RFC). Inclusión de diversos modelos
de materia oscura y energía oscura en los programas numéricos,
y estudio de su influencia en la RFC; de igual manera, utilización
de los datos experimentales para obtener restricciones a los valores
de los parámetros libres de los modelos propuestos. Elaboración
de paquetes didácticos y notas de curso para ser incluidas
en cursos de Cosmología
impartidos en el país.
We show below some references where to study the basic elements
to understand the physics behind the CMB power spectrum.
-Scott Dodelson, Modern Cosmology,
Cambridge University Press.
-Wayne Hu, PhD thesis, also available at: astro-ph/9508126

(go to section CMB)
As for pedagogical notes on Cosmology, you will find some proposals
and original excersises in the following web pages:
http://www.iafe.uba.ar/relatividad/gangui/cosmocurso/
http://www.astro.uiuc.edu/~pmricker/sccp/links.html
If you have recently taught CMB
physics in any Cosmology course, please share your notes with
us!
For numerical programs and
advanced software for the analysis of the CMB signal, go to the
web page LAMBDA
http://lambda.gsfc.nasa.gov/
In particular, click on the link CMB tools, where you will find
the newest software to produce theoretical power spectrum for
different cosmological parameters. Actually, there are two on-line
versions of cmbfast and CAMB, two of the most popular numerical
programs for the study of CMB anisotropies.
But it is always better to try them by yourself! Go to the respective
webpages
http://www.cmbfast.org/
http://www.cmbeasy.org/
http://camb.info/
and download, compile and run the source files in your own computer.
In most cases, you won't need more than an hour to set up the
CMB codes (if you already have some experience with Unix and Linux
systems, of course!).
For a recent program for CMB, take a look at PICO
http://www.astro.uiuc.edu/~bwandelt/pico/
which was recently posted in the specialized literature.
Let us know your experience with CMB codes!
People at IAC interested
in the study and development of CMB software is listed below.
