The kinematic footprints of five stellar streams in Andromeda's halo

Chapman, S. C.; Ibata, R.; Irwin, M.; Koch, A.; Letarte, B.; Martin, N.; Collins, M.; Lewis, G. F.; McConnachie, A.; Penarrubia, J.; Rich, R. M.; Trethewey, D.; Ferguson, A. M. N.; Huxor, A.; Tanvir, N. (2008-10)

(abridged) We present a spectroscopic analysis of five stellar streams (`A', `B', `Cr', `Cp' and `D') as well as the extended star cluster, EC4, which lies within streamC, all discovered in the halo of M31 from our ...

The kinematic identification of a thick stellar disc in M31

Collins, M. L. M.; Chapman, S. C.; Ibata, R. A.; Irwin, M. J.; Rich, R. M.; Ferguson, A. M. N.; Lewis, G. F.; Tanvir, N.; Koch, A. (2010-10-25)

We present the first characterization of a thick disc component in the Andromeda galaxy (M31) using kinematic data from the DEIMOS multi-object spectrograph instrument on Keck II. Using 21 fields in the South West of the ...

A kinematic study of the Andromeda dwarf spheroidal system

Collins, Michelle L. M.; Chapman, Scott C.; Rich, R. Michael; Ibata, Rodrigo A.; Martin, Nicolas F.; Irwin, Michael J.; Bate, Nicholas F.; Lewis, Geraint F.; Peñarrubia, Jorge; Arimoto, Nobuo; Casey, Caitlin M.; Ferguson, Annette M. N.; Koch, Andreas; McConnachie, Alan W.; Tanvir, Nial (2013-02-26)

We present a homogeneous kinematic analysis of red giant branch stars within 18 of the 28 Andromeda dwarf spheroidal (dSph) galaxies, obtained using the Keck I LRIS and Keck II DEIMOS spectrographs. Based on their g-i ...

A kinematically selected, metal-poor stellar halo in the outskirts of M31

Chapman, S. C.; Ibata, R.; Lewis, G. F.; Ferguson, A. M. N.; Irwin, M.; McConnachie, A.; Tanvir, N. (2006-12-10)

We present evidence for a metal-poor, [Fe/H]$\sim-1.4$ $\sigma$=0.2 dex, stellar halo component detectable at radii from 10 kpc to 70 kpc, in our nearest giant spiral neighbor, the Andromeda galaxy. This metal-poor sample ...

KINETIC STUDY OF CHEMICAL LOOPING COMBUSTION USING IRON AS AN OXYGEN CARRIER

Amir, Naji (2011-12-08)

Over the past few decades, combustion of fossil fuels has released greenhouse gases such as CO2 and NOx into the atmosphere. It has been realized that a mean temperature increase of the Earth, also known as global warming, ...

Kinetics and benefits of employing UV light for the treatment of aqueous ammonia in wastewater

Bergese, John (2013-08-21)

Nitrogen compounds, such as aqueous ammonia, are a widespread problem in the wastewater industry as they are toxic to numerous aquatic life, cause eutrophication, and contribute to various environmental concerns. Environment ...
