HST Low Resolution Stellar Library
Tathagata Pal, Islam Khan, Guy Worthey +2
Hubble Space Telescope's (HST) Space Telescope Imaging Spectrograph (STIS) targeted 556 stars in a long-running program called Next Generation Spectral Library (NGSL) via proposals…
Scattered Light in STIS Grating G230LB
Guy Worthey, Tathagata Pal, Islam Khan +2
The G230LB grating used with STIS's CCD detector scatters red light. In red objects, the scattered light mingles with the ultraviolet signal, causing spurious short-wavelength flux…
(P)reheating Effects of the Kähler Moduli Inflation I Model
Islam Khan, Aaron C. Vincent, Guy Worthey
We investigate reheating in the string-theory-motivated Kähler Moduli Inflation I (KMII) potential, coupled to a light scalar field and produce constraints and forecasts based…
(P)reheating Effects of a Constrained Kähler Moduli Inflation Model
Islam Khan, Guy Worthey, Aaron C. Vincent
In this talk, I discuss the effects, viability, and predictions of the string-theory-motivated Kähler Moduli Inflation I (KMII) potential, coupled to a light scalar field , whic…
Hot Star Extension to the Hubble Space Telescope Stellar Spectral Library
Islam Khan, Guy Worthey
Libraries of stellar spectra find many uses in astrophysics, from photometric calibration to stellar population synthesis. We present low resolution spectra of 40 stars from 0.2 mi…
Numerical Solution of a Singularly - Perturbed Boundary-Value Problems by Using A Non-Polynomial Spline
Islam Khan, Tariq Aziz
We consider a non-polynomial cubic spline to develop the classes of methods for the numerical solution of singularly perturbed two-point boundary value problems. The proposed metho…
