For two decades, the international Gemini Observatory has
powered astronomical discovery for the entire U.S. community and
the international Gemini partnership. Gemini’s twin 8.1m
optical/infrared telescopes provide nightly access to both...
Low-frequency Alfvénic turbulence is a leading candidate to
explain the heating of the solar corona and launching of the fast
solar wind. A sufficiently energetic source of such motions is
observed near the coronal base and in-situ measurements...
Abstract 1: In this talk I will first briefly review recent
developments in using forward modeling techniques combined with the
likelihood from effective theory of large-scale structure to
extract cosmological information from galaxy clustering. I...
It has been suggested that the weak magnetic field hosted by the
intergalactic medium (IGM) in voids is a relic from the early
Universe. If so, the modern-day strength and coherence length of
such fields could be “predicted” from reasonable...
Weak gravitational lensing of the large scale structure of the
Universe has been identified as a powerful way to learn about dark
matter and dark energy, two largely unknown components of the
Universe that make up 95% of its matter-energy contents...
Recent radio observations of inflowing and outflowing plasma in
the vicinity of supermassive black holes are linked to simple
phenomenological models via general relativistic
magnetohydrodynamic simulations through a methodology called
"Observing"...
One of the strongest predictions of the standard cold dark
matter paradigm is the hierarchy of structure down to Earth-mass
scales. However, individual self-bound clumps of dark
matter--"halos"--are difficult to detect directly. Instead, we
use...
