We present a search for gravitational waves from the coalescence of binaries which contain at least one subsolar mass component using data from the LIGO and Virgo observatories through the completion of their third observing run. The observation of a merger with a component below 1M would be a clear sign of either new physics or the existence of a primordial black hole population; these black holes could also contribute to the dark matter distribution. Our search targets binaries where the…

Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics
Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture scientific questions

Search for Gravitational Waves from the Coalescence of Subsolar-Mass Binaries in the First Half of Advanced LIGO and Virgo's Third Observing Run.
TLDR
A search for gravitational waves from the coalescence of subsolar-mass black hole binaries using data from the first half of Advanced LIGO and Virgo's third observing run is presented and limits are demonstrated to constrain arbitrary models of the primordial black hole mass distribution and merger rate.
Search for Gravitational Waves from the Coalescence of Subsolar Mass and Eccentric Compact Binaries
We present a search for gravitational waves from subsolar mass compact-binary mergers that allows for nonnegligible orbital eccentricity. Subsolar mass black holes are a signature of primordial
Search for Gravitational Waves from High-Mass-Ratio Compact-Binary Mergers of Stellar Mass and Subsolar Mass Black Holes.
TLDR
The first search for gravitational waves from the coalescence of stellar mass and subsolar mass black holes with masses between 20-100  M_{⊙} and 0.01-1’s’(10-10^{3}‬‬M_{J}), respectively is presented, with a 90% upper limit on the rate of mergers.

Search for Subsolar Mass Ultracompact Binaries in Advanced LIGO's Second Observing Run.
TLDR
A search for subsolar mass ultracompact objects in data obtained during Advanced LIGO's second observing run is presented, and constraints on the merger rate and dark matter fraction may be extended to arbitrary black hole population models that predict subsolarmass binaries.
