PyMorph: Automated Galaxy Structural Parameter Estimation using Python
Vinu Vikram, Yogesh Wadadekar, Ajit K. Kembhavi +1
We present a new software pipeline -- PyMorph -- for automated estimation of structural parameters of galaxies. Both parametric fits through a two dimensional bulge disk decomposit…
A Cosmological Model with Fermionic Field
R. Rakhi, G. V. Vijayagovindan, K. Indulekha
In this work, a cosmological model inspired by string/M- theory with fermionic field is taken into consideration. Here it is investigated whether the introduction of a non-Dirac fe…
Quantitative measure of evolution of bright cluster galaxies at moderate redshifts
Vinu Vikram, Yogesh Wadadekar, Ajit K. Kembhavi +1
Using archival data from the Hubble Space Telescope, we study the quantitative morphological evolution of spectroscopically confirmed bright galaxies in the core regions of nine cl…
A Cosmological Model with Fermionic Field and Gauss-Bonnet Term
R. Rakhi, G. V. Vijayagovindan, Noble P. Abraham +1
In this work, a cosmological model inspired by string theory with Gauss-Bonnet term coupled to the fermionic field is taken into consideration. The self-interaction potential is co…
Super-reflection of light from a random amplifying medium with disorder in the complex refractive index : Statistics of fluctuations
S. Anantha Ramakrishna, E. Krishna Das, G. V. Vijayagovindan +1
The probability distribution of the reflection coefficient for light reflected from a one-dimensional random amplifying medium with {\it cross-correlated} spatial disorder in the r…
