The Optical Green Valley vs Mid-IR Canyon in Compact Groups
Lisa May Walker, Natalie Butterfield, Kelsey Johnson +7
Compact groups of galaxies provide conditions similar to those experienced by galaxies in the earlier universe. Recent work on compact groups has led to the discovery of a dearth o…
Star Clusters in Tidal Debris
Michael Rodruck, Jane Charlton, Sanchayeeta Borthakur +13
We present results of a Hubble Space Telescope (HST) UBVI-band study of star clusters in tidal tails, using new WFC3 and ACS imaging to complement existing WFPC2 data. We survey 12…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
A Tale of Two Tails: Exploring Stellar Populations in the Tidal Tails of NGC 3256
Michael Rodruck, Iraklis Konstantopoulos, Karen Knierman +7
We have developed an observing program using deep, multiband imaging to probe the chaotic regions of tidal tails in search of an underlying stellar population, using NGC 3256's 400…
Tidal Tails of Minor Mergers II: Comparing Star Formation in the Tidal Tails of NGC 2782
Karen Knierman, Paul Scowen, Todd Veach +5
The peculiar spiral NGC 2782 is the result of a minor merger with a mass ratio ~4:1 occurring ~200 Myr ago. This merger produced a molecular and HI rich, optically bright Eastern t…
The SAMI Galaxy Survey: a new method to estimate molecular gas surface densities from star formation rates
Christoph Federrath, Diane M. Salim, Anne M. Medling +16
Stars form in cold molecular clouds. However, molecular gas is difficult to observe because the most abundant molecule (H2) lacks a permanent dipole moment. Rotational transitions…
The SAMI Galaxy Survey: Can we trust aperture corrections to predict star formation?
Samuel Nathan Richards, Julia Bryant, Scott Croom +21
In the low redshift Universe (z<0.3), our view of galaxy evolution is primarily based on fibre optic spectroscopy surveys. Elaborate methods have been developed to address aperture…
The Detailed Science Case for the Maunakea Spectroscopic Explorer: the Composition and Dynamics of the Faint Universe
Alan McConnachie, Carine Babusiaux, Michael Balogh +173
MSE is an 11.25m aperture observatory with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. More than 3200 fibres will feed spectrograph…
The SAMI Galaxy Survey: Global stellar populations on the size-mass plane
Nicholas Scott, S. Brough, Scott M. Croom +20
We present an analysis of the global stellar populations of galaxies in the SAMI Galaxy Survey. Our sample consists of 1319 galaxies spanning four orders of magnitude in stellar ma…
