We present a search for continuous gravitational-wave emission due to r-modes in the pulsar PSR J0537-6910 using data from the LIGO-Virgo Collaboration observing run O3. PSR J0537-…
Don't Panic! Closed String Tachyons in ALE Spacetimes
A. Adams, J. Polchinski, E. Silverstein
We consider closed string tachyons localized at the fixed points of noncompact nonsupersymmetric orbifolds. We argue that tachyon condensation drives these orbifolds to flat space…

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1378
We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced LIGO and Advanced Virgo during O3a, the fi…
All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369
Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…
Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…

Gravitational-wave constraints on the equatorial ellipticity of millisecond pulsars
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1333
We present a search for continuous gravitational waves from five radio pulsars, comprising three recycled pulsars (PSR J0437-4715, PSR J0711-6830, and PSR J0737-3039A) and two youn…
Population Properties of Compact Objects from the Second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1338
We report on the population of the 47 compact binary mergers detected with a false-alarm rate 1/yr in the second LIGO--Virgo Gravitational-Wave Transient Catalog, GWTC-2. We observ…

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1588
We present results of three wide-band directed searches for continuous gravitational waves from 15 young supernova remnants in the first half of the third Advanced LIGO and Virgo o…
Extension of the particle x-ray coincidence technique: The lifetimes and branching ratios apparatus
L. J. Sun, J. Dopfer, A. Adams +11
The particle x-ray coincidence technique (PXCT) was originally developed to measure average lifetimes in the ~s range for proton-unbound states populated by elec…
A ground state Al halo is unlikely
E. A. M. Jensen, J. S. Nielsen, B. S. O. Johansson +13
We report the decisive resolution of the ground state spin and parity of the proton-dripline nucleus Al, a prime candidate for a proton halo. The resolution stems from the f…
Things Fall Apart: Topology Change from Winding Tachyons
A. Adams, X. Liu, J. McGreevy +2
We argue that closed string tachyons drive two spacetime topology changing transitions -- loss of genus in a Riemann surface and separation of a Riemann surface into two components…
