Theoretical physicist @IITKanpur. Curious about the building blocks of the universe.

[Martin Bauer @martinmbauer]

Two pieces of evidence for dark matter that have nothing to do with rotation curves:

1. Early Universe: Use a CMB simulator to see what the early Universe looked like if there was no dark matter and compare with what we measure

Play around:

🔔IceCube results to be published in @ScienceMagazine tomorrow!

For the first time, IceCube found evidence of high-energy neutrino emission from our galaxy ➡️ https://t.co/ErPz4zJyMi

[CERN @CERN]

@FASERexperiment recently observed the first collider #neutrinos at the #LHC.
The observation had a statistical significance of roughly 16 sigma, far exceeding 5 sigma, the threshold for discovery in #particlephysics.

Thermalization in the presence of a time-dependent dissipation and its impact on dark matter production. (arXiv:2302.06654v1 [hep-ph]) relevance:100% https://t.co/VHeC22WMPk #darkmatter @debtosh

Hypothetical accelerator-produced light scalar particles, within a mass
range around 25 MeV, are for the first time ruled out as being all of the
dark matter by the COHERENT CsI Detector at the Spallation Neutron Source https://t.co/gAe7NB8fXD #OpenAccess

[IIT Kanpur Physics @IITKphysics]

The Annual Research Scholar Day of the Dept of Physics, IIT Kanpur is starting today and will continue for the next two days. During this event, the Jagadiswar Mohanty Lecture will be delivered by Prof. Arindam Ghosh @ArindamPhysics tomorrow morning 28th January. All are welcome

The 2020 @XENONexperiment electronic recoil excess (pink) was not seen in a follow-up XENONnT experiment (red) nor in a PandaX experiment.

A search for dark matter annihilation signals from a new gamma-ray survey @hesstelescopes of the Galactic Center sets new exclusion limits on the #darkmatter annihilation cross section https://t.co/TzQF2FGNDD

It's here–the deepest, sharpest infrared view of the universe to date: Webb's First Deep Field.

Previewed by @POTUS on July 11, it shows galaxies once invisible to us. The full set of @NASAWebb's first full-color images & data will be revealed July 12: https://t.co/63zxpNDi4I

[LZ Dark Matter @lzdarkmatter]

There was no evidence for a dark matter signal in our first science run, so we have set world-leading constraints on WIMP properties.

Solid black: observed limit
Dashed-black: median expected sensitivity

🚨The image shows a bright ring around a spot of darkness, a spot we have come to understand as a shadow of a black hole, the direct visual evidence of the black hole's existence. https://t.co/MrDlVNE9Sc

The wait is over. Meet the black hole at the center of our galaxy.

[Marcos Santander @jmsantander]

A new astrophysical neutrino event candidate was detected ~1 hr ago by the @uw_icecube observatory at the South Pole. No obvious high-energy counterparts for this event, but we're looking! #neutrino

An in-depth analysis on confirmation bias.

[Matthew Shallenberger @mjshally]

This whole "the NYT ruined Wordle!" thing is a great case study in confirmation bias. It also gives us some insight into human nature that helps explain how conspiracy theories work.
