A package to simulate supernova surveys in the rest frame Near Infrared

Currently used for cosmology with Euclid, however, it can be extended to any filter-set (JWST,WFIRST being some of the first examples)

Three main Strategies:

  1. Euclid DDF-only (with optical data)
  2. Euclid dedicated survey
  3. Euclid DDF + JWST for high-z anchor

Dependencies astropy, sncosmo

Installation:

git clone https://github.com/sdhawan21/euclidIR.git

cd euclidIR

python setup.py install

Installation for cosmology likelihood computation:

Depends on pymultinest install the python wrapper pip install pymultinest (--user if no root privileges)

Multinest installation Download source from Johannes Buchner's github page

cd Multinest

mkdir build

cd build

sudo cmake .. && sudo make

run demo files to check

Redshift Distributions (a short guide):
  1. EuclidDeep are the deep drilling fields redshift distribution, they do not inlcude a low- redshift anchor unless explicitly specific with 'lowz' in the title
  2. EuclidDed is the dedicated NIR i-band survey with Euclid
  3. EuclidDDF+JWST is a combination of low-z with Euclid and higher-z with JWST
  4. redshift_uniform is a uniform distribution U(0, zmax) as a 'fake' test scenario
  5. JLA_z is the Betoule et al. 2014 distribution
  6. 'z_euclid_100d_lowz.dat' is a shorter survey with a low-z anchor from the ground
  1. euclid + 'survey time' + 'lowz anchor redshift'+'N_SN' in the anchor
Filter set sources:

LSST: SNANA, R.Kessler Euclid: P. Astier, LPNHE Supernova JWST : Built-in to SNCosmo (K. Barbary)
