Abstract.Archaeological Roman lead (Pb) is known to be a suitable material for shielding experimental apparata in rare event searches. In the past years the intrinsic radiopurity of this material was investigated using different technologies. In this work we applied the latest advancements in cryogenic techniques to study the bulk radiopurity of a 1cm^3 sample of archaeological Roman Pb. We report the lowest ever measured limit on 210Pb content in Roman Pb, with a concentration lower than 715… 
Characterization of a large mass archaeological lead-based cryogenic detectors for the RES-NOVA experiment
One of the most energetic events in the Universe are core-collapse Supernovae (SNe), where almost all the star’s binding energy is released as neutrinos. These particles are direct probes of the
Production and characterisation of a $$\hbox {PbMoO}_4$$ cryogenic detector from archaeological Pb
We operated a $$\hbox {PbMoO}_4$$ scintillating cryogenic detector of 570 g, produced with archaeological lead. This compound features excellent low temperature characteristics in terms of light
Neutrino observatory based on archaeological lead
We propose the RES-NOVA project, which will hunt neutrinos from core-collapse supernovae (SN) via coherent elastic neutrino-nucleus scattering (CEνNS) using an array of archaeological lead (Pb) based
PbMoO4 Synthesis from Ancient Lead and Its Single Crystal Growth for Neutrinoless Double Beta Decay Search
A powder synthesis of PbMoO4 (PMO) from ancient lead (Pb) and deeply purified commercial MoO3 powders was performed using a wet chemistry technique to achieve the low radioactivity scintillator for
Search for Majorana neutrinos exploiting millikelvin cryogenics with CUORE
The possibility that neutrinos may be their own antiparticles, unique among the known fundamental particles, arises from the symmetric theory of fermions proposed by Ettore Majorana in 19371. Given

Results on 82Se 2νββ with CUPID-0 Phase I
The nucleus is an extraordinarily complex object where fundamental forces are at work. The solution of this many-body problem has challenged physicists for decades: several models with complementary
RES-NOVA sensitivity to core-collapse and failed core-collapse supernova neutrinos
RES-NOVA is a new proposed experiment for the investigation of astrophysical neutrino sources with archaeological Pb-based cryogenic detectors. RES-NOVA will exploit Coherent Elastic neutrino-Nucleus
