✨Good Time, Bad Time: GTI/BTI :)

In my continued journey with Stingray.jl During GSoC 2025, this phase focused on a core aspect of high-energy astrophysics: time filtering using GTIs (Good Time Intervals) and BTIs (Bad Time Intervals) . After a productive discussion with my mentor @matteobachetti during our meet, I dove into implementing and refining functionality around GTIs—an essential tool in the timing analysis of astrophysical data. What Are GTIs and BTIs? GTIs define intervals during which the data is considered reliable—free of contamination, instrument artifacts, or observational interruptions. BTIs are the complementary regions—gaps between GTIs that typically represent unusable or noisy time segments. Correct handling of these intervals is critical, especially in X-ray timing , where even small artifacts can skew power spectra, light curves, and periodograms. Worked on Features this week I extended and validated the implementation of GTI filtering in both EventList and LightCurve structu...

🌟 Things Are Getting Interesting!!

Hey everyone! If you’ve read my first blog , you already know how this journey started — with nervous excitement, inspiring mentors, and my deep love for astronomy. Since then, things have only gotten more interesting — and yes, more challenging, but in the best way possible! Developing, Debugging, and Growing These past few weeks have felt like a whirlwind of beauty. I’ve found myself diving deeper into spectral analysis, implementing windowing techniques, exploring real research articles, and most excitingly, contributing to the actual development of functions inside Stingray.jl! A New Adventure: EventList and GTI Handling Now comes the exciting part — I’ve been working on mission support ,  PR #49 , where I got to play around with EventList structures. I made a minimal version   EventList that could read test files, handle metadata smartly, and even filter events using GTIs (Good Time Intervals). My mentor @fergus and I created a   filter_time! ...

Beginning of GSoC 2025

Image
Hello everyone, and welcome to my first blog! I’m very excited to begin this journey. Since childhood, I’ve been deeply fascinated by astronomy , and today, I finally get to express that passion through writing and sharing my learning experiences with such a great community. A Memorable Start – Meeting My Mentors This week started off on a truly inspiring note. On May 23rd , I had the opportunity to meet my mentors—individuals with deep expertise and experience in the field. At first, I was a bit nervous and hesitant. But the moment the session began, all my fear started fading away. We began with short introductions and then quickly moved on to discussing plans for the upcoming work. I had a few doubts—some of which I felt were too basic or weird to ask—but I’m so glad I did! My mentors answered them with such clarity and patience. They even gave me valuable suggestions for improving one of my current functions (called recpiec ) and helped us finalize a workflow to proceed with. Learn...

Black Holes: Nature's Most Mysterious Phenomena

  Introduction Black holes are among the most fascinating and enigmatic objects in the universe. They are regions in space where gravity is so strong that nothing, not even light, can escape from their grasp. The concept of a black hole was first predicted by Albert Einstein’s theory of general relativity, yet it took decades before any solid evidence of their existence was discovered. Today, black holes not only captivate scientists but also spark the imagination of everyone interested in the cosmos. In this blog, we’ll explore what black holes are, how they form, and their significance in the universe. What is a Black Hole? A black hole is essentially a region of space where the gravitational pull is so immense that even light cannot escape. This happens when a massive amount of matter is compressed into a tiny area, creating an extreme warping of spacetime. At the center of a black hole lies a point called the singularity , where matter is infinitely dense, and our current under...
