The pattern in the Standard Model (SM) charges can be traced to an ambiguity in the gauge group of the SM. The easiest way to resolve this ambiguity would be to discover a particle with electric charge that is an integer multiple of e/6 (beyond +/- e, 0). The discovery of such fractionally charged particles would also challenge and potentially rule out many minimal unification models. In this...

Millicharged particles (mCPs) represent a striking example of exotic phenomenology stemming from a relatively simple hidden sector Dark Matter model. Moreover, fractionally charged particles remain subject to relatively few constraints from either indirect or direct observations at masses close to the electroweak scale. The milliQan experiment at the Large Hadron Collider is a subdetector of...

Accurate signal predictions are essential for interpreting and optimizing fixed-target searches for new physics. Even in minimal models such as the dark photon ($A'$) or millicharged particles (mCPs), theoretical uncertainties in hadronic production can be substantial. We introduce a data-driven framework that predicts both the rate and kinematic distributions of $A'$ and mCP production...

Light scalars mixing with the Higgs boson are one of the few renormalizable dark sector portals, and are featured in many BSM models. Considering scalars produced in core-collapse supernovae allows one to extend sensitivity to far smaller couplings than can be probed at accelerators, which are fundamentally limited by luminosity. However, existing supernova bounds have left a substantial gap...

Pulsar timing array experiments use high-precision timing of millisecond pulsars in the Milky Way to search primarily for nHz-frequency gravitational waves. Timing data is also sensitive to the presence of ultralight dark matter (ULDM) in the Galaxy: the ultralight field behaves as a classically oscillating wave that creates metric perturbations, imprinting a deterministic oscillatory...

Axion-like particles (ALPs) appear in many beyond-the-Standard-Model theories, either as candidates for dark matter or as partners of the axion that explains the apparent conservation of charge-parity symmetry, known as the strong CP problem. In this talk, I will present a novel method for probing ALPs using eclipsing binary systems which can serve as an astrophysical realization of...

Isolated neutron stars (INS) are the simplest kinds of neutron stars, but only seven have been discovered and confirmed. We show that in the near future, the Vera Rubin Observatory (VRO) will be able to identify new INS candidates. In this talk, we outline a proof of concept for predicting the signals from INS as seen by VRO, as well as a method for separating those signals from backgrounds....
