Serena Giardino is a PhD student in the “Quantum Gravity and Unified theories” department.

Her work focuses on understanding the true nature of gravity. The standard model of cosmology, based on Einstein’s general relativity, provides an accurate picture only by postulating the existence of dark matter and dark energy. She explores modified theories of gravity that might explain the accelerated expansion of the universe without resorting to dark energy. She tries to understand the cosmological implications of going beyond Einstein’s theory, for both the early and the late universe. Since she started her postdoc, she has also been working on lensing of gravitational waves and how it can be used for testing modified gravity theories.

This #astro review paper seems to be quite interesting: https://arxiv.org/pdf/2501.17006
Everything you want to know about #MOND. I had a very nice chat with the second author on Tuesday and enjoyed the open-minded discussions on the overlap of dark-matter and MOND phenomenology.
Enjoy reading!

#Waiting4WinterSolstice part 4 -- hopefully today's talk by @EU_phil_cosmo will draw some more likes, as it's tackling the question what we call "the missing mass" in astrophysics. Some say it's #DarkMatter, others call it #ModifiedGravity. Enjoy: https://youtu.be/2TBiTXqgczY?si=wbiBlsPsL3HRU9nI

Is the Skordis & Zlosnik idea just "baroque dark matter" or is abandoning locality necessary to get rid of sth we only have indirect evidence for?
What do you think about the paper?

For all of you who are stuck in cold dark winter weather, have a look at this workshop starting in about 15 mins, focussing on the bright side of the cosmos: does #cosmology need #darkmatter ? I am curious about the status-quo!

Could Modified Gravity Be the Answer to Planet 9?
Modified Newtonian Dynamics (or MOND) theory has already been proven accurate for things like understanding galactic rotation. But what about using it closer to home?

Conclusive Evidence for Modified Gravity: Collapse of Newton’s and Einstein’s Theories in Low Acceleration
A recent study reveals that the orbital motions of widely separated binary stars, or “wide binaries,” break down the standard model of gravity at low accelerations. Analyzing data from 26,500 wide binaries, researchers found that accelerations below one nanometer per second squared deviate from Newton’s and Einstein’s gravitational laws.
