Multimessenger astronomy with the Einstein Telescope
Gravitational waves (GWs) are expected to play a crucial role in the
development of multimessenger astrophysics. The combination of GW observations
with other astrophysical triggers, such as from gamma-ray and X-ray satellites,
optical/radio telescopes, and neutrino detectors allows us to decipher science
that would otherwise be inaccessible. In this paper, we provide a broad review
from the multimessenger perspective of the science reach offered by the third
generation interferometric GW detectors and by the Einstein Telescope (ET) in
particular. We focus on cosmic transients, and base our estimates on the
results obtained by ET's predecessors GEO, LIGO, and Virgo.Comment: 26 pages. 3 figures. Special issue of GRG on the Einstein Telescope.

Experimental Signatures of Anomaly Induced DCC Formation
We discuss characteristic experimental signatures related to the formation of
domains of disoriented chiral condensate (DCC) triggered by the axial anomaly
in relativistic heavy ion collisions. We predict that the enhancement of the
fraction of neutral pions compared to all pions depends on the angle of
emission with respect to the scattering plane and is concentrated at small
transverse momentum and small rapidity in the center-of-mass frame. The
anisotropy with respect to the reaction plane is also observable in the
inclusive photon distribution.Comment: 11 pages, 4 figures, REVTEX, discussion on photon distribution added,

Phenomenology of Multi-W Processes in Cosmic Rays
We report on a study of the potential of various cosmic ray physics
experiments to search for Standard Model processes involving the
nonperturbative production of O(30) weak gauge bosons. Whereas present and
near-future experiments are insensitive to proton-induced processes,
neutrino-induced processes give rise to promising signatures and rates in
AMANDA, DUMAND, MACRO and NESTOR provided that a cosmic neutrino flux exists at
levels suggested by recent models of active galactic nuclei. The Fly's Eye
currently constrains the largest region of parameter space characterizing
multi-W phenomena.Comment: (Invited talk presented by A. Ringwald at 17th Johns Hopkins Workshop

Deeper, Wider, Sharper: Next-Generation Ground-Based Gravitational-Wave Observations of Binary Black Holes
Next-generation observations will revolutionize our understanding of binary
black holes and will detect new sources, such as intermediate-mass black holes.
Primary science goals include: Discover binary black holes throughout the
observable Universe; Reveal the fundamental properties of black holes; Uncover
the seeds of supermassive black holes.Comment: 14 pages, 3 figures, White Paper Submitted to Astro2020 (2020
