Real-time Cosmology with High Precision Spectroscopy and Astrometry
Sukanya Chakrabarti, Anthony H. Gonzalez, Steve Eikenberry +9
Breakthroughs in physics and astrophysics are often driven by technological advances, with the recent detection of gravitational waves being one such example. This white paper focu…
Gemini/GMOS Spectra of Globular Clusters in the Leo Group Elliptical NGC 3379
Michael Pierce, Michael A. Beasley, Duncan A. Forbes +8
We have obtained Gemini/GMOS spectra for 22 GCs associated with NGC 3379. We derive ages, metallicities and alpha-element abundance ratios from simple stellar population models usi…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
Gemini North Adaptive Optics (GNAO) facility overview and status updates
Gaetano Sivo, Julia Scharwächter, Manuel Lazo +54
The Gemini North Adaptive Optics (GNAO) facility is the upcoming AO facility for Gemini North providing a state-of-the-art AO system for surveys and time domain science in the era…
Measuring the Hubble Constant Near and Far in the Era of ELT's
Rachael L. Beaton, Simon Birrer, Ian Dell'Antonio +7
Many of the fundamental physical constants in Physics, as a discipline, are measured to exquisite levels of precision. The fundamental constants that define Cosmology, however, are…
Gemini/GMOS Spectra of Globular Clusters in the Virgo Giant Elliptical NGC 4649
Michael Pierce, Terry Bridges, Duncan A. Forbes +8
NGC 4649 (M60) is one of a handful of giant Virgo ellipticals. We have obtained Gemini/GMOS spectra for 38 GCs associated with this galaxy. Applying the multi-index chi^2 minimisat…
