All’inizio dell’universo vi fu… no, non un “big bang”! La teoria del Big Bang spiega cosa sia successo dopo il “bang”, come l’universo si sia raffreddato ed espanso.

La teoria dell’inflazione ci spiega cosa sia successo prima di questo periodo e ci dice che l’universo non può essere nato dall’esplosione di una singolarità (un puntino). E da cosa allora?

Più indietro dell’epoca inflazionaria non possiamo andare. Come sia nato l’universo rimane uno dei tanti misteri della scienza non ancora risolti.

Dark matter is out there
Find it is all we care

WIMPs, axions, dark photons...
We are looking for the latter bosons

Kinetic mixing allows the dark
to become Standard and make a “spark”!

A multilayer dielectric haloscope as detector
equipped with a SPAD as light collector.

1/ Image
A stack of dielectric layers, in total 46,
enables the dark to standard photon mix

Converted a photon?

The aspherical lens to focus it
The spad to then count the hit

As no significant excess we get
90% C.L. upper limits we set

2/ ImageImage
The name of the detector is MuDHÍ مضيء
And it’s the first dark matter experiment in the UAE

Although DM we haven’t found yet
A few goals we have already met

On our paper such achievements, we outline
though not yet peer-reviewed, you can read it on arXiv!
