Glitching pulsars as sources of transient gravitational waves
The spin of neutron stars can be timed with exquisite precision and are seen observationally as pulsars. They are observed to spin-down steadily over long periods but once in a while, they can undergo a rapid and sudden increase in their spin, which is known as a glitch. For some cases, the glitch is followed by a post-glitch recovery. There are several models that predict the emission of conti...

Formation of satellite systems around Jupiter and Saturn
Satellite systems around Jupiter and Saturn have different characteristics. The Saturnian system is dominated by a giant moon, Titan, which holds over 95% of the total mass of Saturnian moons. On the other hand, the Jovian system has four large moons in a compact orbital area, and inner three, Io, Europa and Ganymede, are known to be in resonant orbits. Previous studies have shown that the spec...

A Euclid View of the Intracluster Light in the Perseus Cluster
I will present new state-of-the art observations of the Perseus Cluster taken as part of the Euclid Early Release Observations. This data allows us, for the first time, to characterize the intracluster light (ICL) and intracluster globular clusters (ICGCs) in Perseus out to 600 kpc from the BCG. We find that within 500kpc of the BCG, there are 70,000 globular clusters and that the ICL account...

Portable Fantacies: How to Work with Android-like Devices
Over the past few years, the computing capability of portable devices equipped with ARM processors has expanded exponentially. Yet, despite their growing power, the prevalent Android-like operating systems often confine users to a 'walled garden,' restricting direct interaction with the core Linux functionalities. In this presentation, we will explore the transformative potential of Termux and ...

Biases and uncertainties in quantifying morphology of galaxies at high redshifts with JWST
Observations of high-redshift galaxies with unprecedented detail have now been rendered possible with JWST. However, accurately quantifying their morphology remains uncertain due to potential biases and uncertainties. To address this issue, I used a sample of 1816 nearby DESI galaxies to compute artificial images of galaxies of the same mass located at high redshifts and observed at rest-frame ...
