Cosmological and astronomical measurements give a consistent evidence 
for the existence of dark matter. New particles that could account for 
this non-luminous matter, appear in several theories beyond the standard 
model of particle physics.

Direct detection experiments using liquid xenon have shown a great 
potential to probe the existence of WIMPs (Weakly Interacting Massive 
Particles) via elastic scattering off target nuclei.  XENON1T is a 
dual-phase time projection chamber (TPC) with 2 tons of xenon in the 
target that has been operated from 2016 to 2018. Over the last years, 
XENON1T has set most constraining results on the cross section for the 
interaction of WIMPs with target nuclei. Due to its large mass and 
ultra-low background, the physics case of XENON1T has expanded to 
further rare-event searches.

Recently, results from searches for new physics with low-energy 
electronic recoil data have been reported. The data enables competitive 
searches for solar axions, an enhanced neutrino magnetic moment using 
solar neutrinos, or for bosonic dark matter, among others.
The experiment has been upgraded to XENONnT containing 6 tons of liquid 
xenon inside the TPC. While the commissioning of the new detector is 
currently on-going, the data taking is expected to start this year.  In 
this talk, the XENON1T results and the current status of XENONnT 
commissioning will be presented.
