I'm elated to announce that our work on 'Imprint of local opacity in high energy gamma-ray spectrum of Blazar jet' is now published in ApJL.
I've summarized it in a doodle overlay template inspired by @ClaireLamman.

The creator of Claude Code teaches more about vibe-coding in 30 minutes than most tutorials do in hours.

Save this — it'll change how you build forever.

Hi everyone,

Our recent paper on high energy gamma-ray emission from gravitationally lensed quasar PKS 1830-211 got published earlier this year.

Here are the journal link: https://t.co/oeO0azJLcZ

Velocity distribution of stars in a galaxy

Left : expected assuming only visible matter using GR/Newtons law

Right: observed

Something makes stars far from the centre move much faster then expected 🤔

#DYK: One of @NASA’s superpowers is X-ray vision! Studying X-rays from the cosmos, that is.

All this week, we’ll explore how our telescopes collect X-ray light that comes to us from across the universe and what we learn from studying it. Let’s start with some X-ray 101 … 🧵

GRBs have generally featureless spectra at MeV energies. Edvige Ravasio et al. identify a transient emission line in the MeV spectrum of the bright GRB 221009A; the line evolves in energy and width during the fading phase of the #GRB.

Supermassive black holes at the hearts of active galaxies may be churning out a lot of the universe’s high-energy neutrinos.

[Department of Physics at University of Oxford @OxfordPhysics]

An Oxford-led team has developed a novel method to create plasma 'fireballs' on Earth, mimicking those near black holes and neutron stars. This breakthrough, published in Nature Communications, opens new research avenues in laboratory astrophysics. https://t.co/KlnQJDgDCf

JWST captured the clearest view of Neptune’s rings and 7 of its 14 known moons. Triton, Neptune’s largest moon, appears brighter than the planet in this Webb view.

This work is done with my Supervisor @Amit008_Shukla , Karl Mannheim, Bhargav Vaidya, Biswajit Banerjee.

Also the useful comments by the reviewer helped improve the discussion.

A lazy neutron star.
Are there more? That's the third of its kind.

“It is highly unusual to discover a neutron star candidate emitting radio pulsations in this way. The fact that the signal is repeating at such a leisurely pace is extraordinary.”

And that makes three: Our colleagues at @Sydney_Uni and @CSIRO_ATNF have found a third slowly repeating object deep in space. We caught up with ICRAR co-authors @ColourfulCosmos and Sam McSweeney to find out why that's a big deal:

You’re likely reading this on a screen with millions of pixels. But what if you only had 36?

That’s plenty for the Resolve instrument on @JAXA_en’s XRISM!

Watch this video to learn how just 36 pixels can help us capture revolutionary science. Read more: https://t.co/Qn4LsKggl5

New timelapses of two of the most famous objects in the sky — the Crab Nebula & Cassiopeia A! X-ray data collected by Chandra over about two decades shows dramatic changes in the debris & radiation remaining after the explosion of two massive stars. More: https://t.co/MV4XHz062m

Violent environments around some of the most humongous black holes provide exciting opportunities for studying extreme science cases. I recently wrote an article about my research, which was published in a UK-based journal. Feel free to explore.

So what does our spiral pattern tell us about the magnetic fields around Sagittarius A*? The field is actually strong and ordered!
