A CO J = 2-->1 study of the outflow sources GL 490 and NGC 7538 IRS 9

Schella, Jason Walter (Halifax, N.S. : Saint Mary's University, 1991)

This thesis presents new detailed [superscript 12]CO and [superscript 13]CO observations, using 21" resolution, around the two luminous infrared sources GL 490 and NGC 7538 IRS 9. Observations show strong evidence for ...
A multi-transition CO study of the GL 490 outflow

Lee, Siow Wang (Halifax, N.S. : Saint Mary's University, 1992)

The high-velocity GL 490 outflow has been observed at high spatial resolution with the JCMT in three rotational transitions (J = 2[right arrow]1 of HBBW = 21", J = 3[right arrow]2 of HPBW = 15" and J = 6[right arrow] 5)of ...
A multitransitional CO study of NGC7129

Miskolczi, Beverly (Halifax, N.S. : Saint Mary's University, 1998)

New observations of the molecular cloud NGC 7129, in several emission lines of CO, allows an assessment of the effects of recent and ongoing star formation. The CO data is supplemented with limited HCO[superscript +] J = ...
A study of molecular gas associated with the HH24 optical jets

Ma, Lifang (Halifax, N.S. : Saint Mary's University, 1994)

The HH24 complex have been mapped in ¹²CO J=3-2 emission at 14" resolution, using the 15m James Clerk Maxwell Telescope (JCMT) on Manna Kea, Hawaii. The map in ¹²CO J=3-2 shows complicated morphology ...
The evolution of star formation rates in high-redshift galaxies

Marquis, Andrew H. (Halifax, N.S. : Saint Mary's University, 2010)

We use photometric galaxy samples and spectral synthesis models to investigate the ability of three dramatically divergent star formation histories (SFHs) to describe the build-up of stellar mass in galaxy populations ...
Infrared imaging of the sub-millimetre protocluster near NGC 2068 in Orion B

Ruiter, Ashley J. (Halifax, N.S. : Saint Mary's University, 2005)

Sub-millimetre mapping of Orion B (L1630) using SCUBA on the James Clerk Maxwell Telescope has revealed a large population of compact cores (Mitchell et al. 2001). Using the CFHT-IR camera on the Canada-France-Hawaii ...
PHIBSS fibs : a SCUBA2 followup of z ~ 2.5, gas-rich, star forming galaxies

Beanlands, Jennifer K. (Halifax, N.S. : Saint Mary's University, 2015)

Emissions from high redshift (i.e. z ~ 2.5), star forming galaxies provide a unique window into the state the universe at earlier epochs, and how these galaxies evolve over time. Accurate studies of these galaxies, however, ...
Shocked molecular gas in three supernova remnants : W28, W44, 3C391

Font, Andreea (Halifax, N.S. : Saint Mary's University, 1999)

The three supernova remnants, 3C391, W28 and W44, are known to be interacting with their environmental molecular clouds. Our goal in studying such interactions is to determine whether compression by supernova shocks triggers ...
Testing the ergodicity of star formation within galaxies

Smith, Fraser M. (Halifax, N.S. : Saint Mary's University, 2023-08-11)

Part of our understanding of how galaxies evolve is based on individual evolutions inferred from population trends. In its strictest form, this approach implicitly assumes that the star formation properties of galaxies ...
The cool interstellar medium of NGC 5866

Kacprzak, Glenn (Halifax, N.S. : Saint Mary's University, 2005)

The nearly edge---on S0 galaxy NGC 5866 is notable for its massive molecular interstellar medium, prominent central dust lane, and large IRAS 100 micron flux. The galaxy is relatively isolated, and neither the kinematics ...
The star forming core of Mon R2

Giannakopoulou, Jean (Halifax, N.S. : Saint Mary's University, 1993)

In this thesis, the nature of the star forming core of the Mon R2 cloud is investigated using new, high spatial resolution observations. The new data include: maps of [superscript 12]CO J=3[right arrow]2, HCN J=4[right ...
Using the 1.6[mu]m bump to study rest-frame H-band selected galaxies at redshift 2

Sorba, Robert (Halifax, N.S. : Saint Mary's University, 2009)

In this work, we set out to test the feasibility and limitations of using the 1.6[mu]m bump as a photometric redshift indicator and selection technique using publicly available Spitzer/IRAC images in the GOODS fields. We ...
