MAC Telecon, Action List - Wootten

183 GHz - Yun

PR - Wootten

Let's discuss the simulation of the HDF some more. Examples are collected at: the zlines page . Avery has questioned Blitz's contention that SKA will provide a better instrument with which to measure CO at z>3.6. Ignoring linewidth for the moment, let us see a pie diagram--z as the radial coordinate with RA as the angular coordinate, with declination collapsed--showing the galaxies that will be detected in a line. Included here are all CO lines from J=3->2 (none) to J=17->16. I also include CII and NII with the assumption that they will be no brighter than the CO lines, a fairly safe assumption I believe. 352 galaxies are bright enough to be detected in some line or combination of lines in several hours integration. My earlier estimates did not take into account that many of the galaxies are at great distances; there is nearly complete coverage of z at higher redshifts, with several lines within the bandpass for an increasing number of galaxies by the higher redshifts. The diagram is at: http://www.cv.nrao.edu/~awootten/mmaimcal/hizmols.html

Fall 99 Meeting - Wootten

Note that the 12m '30th birthday meeting' will be of substantial interest to our group:

6- 9 Jun 'Imaging at Radio through Submillimeter Wavelengths' meeting in Tucson

As you may know, a meeting of U. S. and European scientists is being planned for the Fall of 1999 in Washington, D. C. The goal of the meeting is to review the scientific program planned for the joint array and how that program interacts with the science goals of other astronomical facilities expected to be operational at the time that the MMA/LSA becomes operational.

Please comment upon the proto schedule for the Science With A Large Millimeter Array meeting at:

LMA99

Science topics for this suggestion were drawn from those identified by the 1997 Thaddeus committee (Task Group on Space Astronomy and Astrophysics, Committee on Astronomy and Astrophysics, Board on Physics and Astronomy, Space Studies Board, Commission on Physical Sciences, Mathematics and Applications, National Research Council) report A New Science Strategy for Space Astronomy and Astrophysics", or by McKee:

McKEE's PROPOSED DRAFT SCIENCE PRIORITIES (12/98)

  • PRIMARY
  • -The large scale structure of the Universe
  • -The formation and evolution of galaxies
  • -The formation and evolution of stars
  • -The formation and evolution of planets, particularly habitable planets
  • SECONDARY
  • -The impact of the astronomical environment on the Earth
  • -The nature of dark matter
  • -The origin of the elements
  • -The formation and evolution of black holes
  • -The origin of high energy particles and photons
  • -The origin and evolution of magnetic fields

We might further limit them to those for which we thought that the MMA would provide deep impact. Modifications and suggestions are welcome.

Action Items 8Mar99

UPCOMING REVIEW: On or before 31 May 1999 we review results from the OVRO and BIMA phase correction systems.

REVIEW: 5 Mar 99 Antenna RFP review. Mangum to represent MMA ImCal. DECISION: 183 GHz or 22 GHz phase correction?

DECISION: Is a nutating secondary necessary?

DECISION: What is the effect of 1/f noise in the HEMT amplifiers of SIS receivers upon our ability to combine total power and interferometric images into a faithful representation of the sky?
