Recent Developments in mm and Sub-mm Interferometry

(Sub)mm Interferometry Applications in Star Formation Research

(Sub-)mm interferometry in massive star-forming regions

(Sub-)mm interferometry is the most favorable technique to investigate the earliest stages of massive star formation. I will outline general applications in that field and discuss results of different sub-topics (hot core chemistry and massive molecular outflows). Furthermore, recent data obtained with the Submillimeter Array will be shown to present the unique capabilities of this new instrume...

Radio-mm-FIR Photometric Redshifts for (sub-)mm Galaxies

We present a comparison between the published optical, IR and CO spectroscopic redshifts of 86 (sub-)mm galaxies and their photometric redshifts as derived from long-wavelength (radio–mm–FIR) photometric data. The redshift accuracy measured for 13 sub-mm galaxies with at least one robustlydetermined colour in the radio–mm–FIR regime and additional constraining upper limits is ∆z ≈ 0.30. This ac...

Fully Differential mm/sub-mm Wave CMOS Amplifiers

This paper presents an effective design methodology and flow, which is validated through three mmwave/sub-mm-wave amplifiers: including W-band LNA with NF=7dB, W-band PA with PAE >11% and D-band amplifier with gain>20dB. The CMOS based amplifiers can be integrated with III-V materials to form heterogeneous integration, such as COSMOS, to achieve the best performance for various applications.

Sub-mm Galaxies in Cosmological Simulations

We study the predicted sub-millimeter emission from massive galaxies in a Λdominated cold dark matter universe, using hydrodynamic cosmological simulations. Assuming that most of the emission from newly formed stars is absorbed and reradiated in the rest-frame far-infrared, we calculate the number of galaxies that would be detected in sub-mm surveys conducted with SCUBA. The predicted number co...
