RIST-12 Lecture : 'Signature Of Dark Energy ' at MU
Date: 18th June, 2015
INVITATION FOR RIST POPULAR TALK
You are cordially invited to attend the monthly popular talk series organized by the RESEARCH INSTITUTE OF SCIENCE AND TECHNOLOGY (RIST), IMPHAL
Title:
SIGNATURE OF DARK ENERGY IN CLUSTER ABUNDANCE
By
Dr. N. Chandrachani
Observatorio Nacional, 20921-400, Rio de Janeiro, RJ, Brazil
Measurements of the cluster abundance as a function of mass and redshift provide an important cosmological test that probe not only the expansion rate but also the growth of perturbations. In this talk the speaker will consider a scalar field dark energy scenario which admits both thawing and freezing solutions from an appropriate choice of the model parameters and show all relevant expressions to calculate the mass function and the cluster number density. The speaker will also discuss the ability of cluster observations to distinguish between these scalar field behaviors and the standard “Lambda CDM” scenario by considering the eROSITA and SPT cluster surveys.
