Akshita's Research

Introduction

Hi! I am a fourth-year physics undergraduate student with a data science minor at IISER Thiruvananthapuram. This github repository contains progress in the projects I have participated in. This repository will be updated with time.

Projects

IUCAA Pune / Project H₀ / 2021

With Prof. Sanjit Mitra and Kanchan Soni

• To understand the inclusion of higher modes to improve parameter estimates
• Injection studies conducted recreating the BBH signal GW150914 over a Gaussian noise
• IMRPhenomPv2, SpinTaylorT5threePointFivePN waveform models employed

AEI Hannover / Tests of GR / 2022

With Dr Frank Ohme and Dr Krishnendu V Nair

• Prediction of the results of the next-generation gravitational-wave detectors (ET and CE)
• Evaluated SNRs for some simulated GW events and
• Analysed SNR dependance on masses and distances of mergers

PHY5132 Project / Estimating the Hubble Parameter / 2022

With Shubham Chury

• To constrain the values of the Hubble parameter
• Analysed the event GW170817 and found posteriors on luminosity distance, psi and phase
• Calculated Bayes factor and compared the the waveform models IMRPhenomPv2, SpinTaylorT4 and IMRPhenomPv2_NRTidal

IISER Thiruvananthapuram, IUCAA Pune / Minor Project / 2023 (tentative)

With Dr Shabnam Iyyani and Dr Apratim Ganguly

• To conduct predictive analysis in the deci-hertz region of gravitational-wave astronomy for DECIGO
