GWSkyNet: a low latency annotation pipeline for the identification of gravitational wave candidates for the next observing run
The accurate and rapid identification of gravitational wave candidates is crucial for follow-up observations of electromagnetic emissions. In run O3, the LIGO/Virgo collaboration released 80 Open Public Alerts. However, the rates of retractions and false alarms point to the need for a complementary model that predicts the nature and origin of OPAs in low latency. I will discuss GWSkyNet, a machine-learning algorithm capable of discerning between signals of astrophysical and terrestrial origin.

Operating principles and performance of a miniature, cold-cycle dilution refrigerator when tilted
Miniature, cold-cycle dilution refrigerators (DRs) are being explored as an alternative to adiabatic demagnetization refrigerators for the cooling of sensors aboard astrophysics balloon missions. In this talk, the design, function, and testing of a miniature, cold-cycle DR manufactured by Chase Cryogenics will be discussed. I will also briefly discuss our research on pulse tube refrigerators, which is part of an effort at NIST to minimize the size and infrastructure requirements of cryostats.

Power and Signal over fiber for DUNE's vertical drift LArTPC
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long baseline (1300 km) neutrino oscillation experiment. Neutrino beam measurements will be performed through near and far detectors. The far detector consists of four modules, installed 1,5 km deep underground, based on Liquid Argon Time Projection Chamber (LArTPC) technology to detect particles. In this talk I will discuss about the Signal and Power over fiber, being developed to operate at the Vertical Drift LArTPC.

A long time ago in a pp collision far, far away: searching for displaced vertices at CMS
Many BSM models predict new long-lived particles (LLPs) that could be produced at the LHC and travel measurable distances before decaying. This talk will focus on a background-free search for LLPs that aims to reconstruct decay vertices inside the CMS beam pipe using charged particle tracks, along with potential future extensions to the search. In addition, this talk will also present studies of silicon pixel sensors that will be installed in the upgraded CMS tracking detector for the HL-LHC.

CCDs for DM and ν detection: past, present and future
This talk will review the use of Charge Coupled Devices (CCDs) in dark matter and neutrino experiments. In addition, it will discuss the Skipper-CCD technology (single-electron counting sensors), results of the ongoing Skipper-CCD experiments, and efforts to build OSCURA (an array of ~20,000 Skipper-CCDs for sub-GeV dark matter search).

Tracing the local dark matter distribution
This talk will review the local dark matter distribution of Milky Way-like galaxies extracted from state-of-the-art cosmological simulations, and its implications for dark matter direct detection. It will also discuss how the dark matter component of the Gaia radially anisotropic stellar population and the Large Magellanic Cloud can impact the results.

The Search for Light Dark Matter with the NEWS-G Detector
The NEWS-G direct dark matter search experiment uses spherical proportional counters (SPC) with light noble gases to explore low WIMP masses. The next phase of the experiment consists of a large 140 cm diameter SPC installed at SNOLAB. This talk will discuss several improvements of the detector, preliminary results of the last campaign, design and construction of the ECUME SPC, and the potential to achieve sensitivity reaching the neutrino floor in light dark matter searches.

Probing the dynamics of high-energy particles in our Universe with multi-messenger observations
Multi-messenger observations of cosmic rays, gamma rays, and neutrinos allow us to study the dynamics of high-energy particles in our Universe in unprecedented detail. This talk will present cases where multi-messenger observations have shown their strength, including the VHE gamma-ray flaring episode observed in the blazar TXS 0506+056 in coincidence with an IceCube neutrino event.
