Astronomy with CARMA Raising our Sites

1. Astronomy with CARMA Raising our Sites

2. CARMA Origins Owens Valley Array • BIMA 9 x 6.1m + OVRO 6 x 10.4m • enhanced research capabilities • hands-on training w. state-of-art instrument • easy access (maintenance & development) • year round operation Berkeley-Illinois-Maryland Array Cedar Flat – March 2004 CARMA Contract: February 2003 U.S. F.S. Site Approval: May 2004 Site Development: 2004 

3. Cedar Flat – elevation 2200m August 2005

4. First Light Enhancements • Better Site - higher elevation • atmospheric transmission x 2, improved phase stability • year-round observing: routinely at 1 mm • Hybrid array – more telescopes, more baselines • increased imaging fidelity, speed, & dynamic range •  enhanced snapshot & mosaicing • wide field mm-wave imaging on scales from 0.13 to 1 • (to 3 with 8 x 3.5 m U Chicago SZA array) • Enhanced performance • upgraded antenna drives, cryogenics, telemetry • hierarchical distributed monitor and control software • Combined resources of partner universities • broad science and technology base

5. Anticipated Developments 2005-2008 • Receivers • lower noise, wideband, dual polarization • (HEMT/SIS/MMIC development programs) • Correlator • expanded COBRA-based (SZA demonstrated) • increased bandwidth - 4 GHz x 2 polarizations • Improved access to CARMA data • automated pipeline image production, user-friendly archive • Implementation of B and A arrays  factor of 2 improvement in sensitivity

6. Array Configurations

7. CARMA Science • Summary of the kind of science that is enabled with references to later talks • CARMA will build on science accomplished • Recall OVRO & BIMA results  MMA in Bahcall Report ultimately  ALMA ( science examples in proposal) • CARMA endorsed in most recent Report –AANM • to study star formation at all epochs etc. • & • to foster the training of students and US capability in mm-wave interferometry at the start of the ALMA era and beyond

8. CARMA for the Community • AANM “to foster…U.S. capability….(in)… ALMA era and beyond” • 30% observing time for the community • representation on Time Allocation Committee • training in mm-wave interferometric observing • CARMA summer school • pipeline and data archive, links to National Virtual Observatory • complements Spitzer, SOFIA, NGST, ALMA in northern hemisphere • Educate leaders for the future • hands on training on state-of-the art instrument • (postdocs, grad students operate array/allocated substantial time) • support US ALMA effort in scientific research • enable strong US technology development program • builds on past success - http:/www.mmarray.org/info.html • (more than 12 professorial faculty directly associated with CARMA) • Public Outreach • Open House, relations with WMRS, local school resource

9. CARMA for the Community • Recall AANM “to foster..” • Is http:/www.mmarray.org/info.html updated with all the young leaders and educators we have produced? • Women and minorities • mm-Wave Community • More than 12 professorial faculty associated with CARMA • Postdocs, grad students allocated substantial array observing time, do most of observing = training • CARMA Summer School • Larger astronomy community • improved accessibility, links to national virtual observatory? • contributions to ALMA from pioneering arrays • CARMA pathfinder role for ALMA • CARMA complements Spitzer, SOFIA, NGST, northern hemisphere complement to ALMA • Public Outreach • Open House, relations with WMRS, local school resource

10. Management & Operations • CARMA Board and SSC • Director & Project Manager/ Asst Dir Operations • U Chicago role • Science, Technical Development, Construction/Operations • Assistant Director Operations –coordinating role • Observing • Students, postdocs main observers • Friend of the Telescope

11. Schedule • More appropriate for Douglas to do all? OR • Summarize status at end of grant period • Comment on pad construction and other outstanding tasks –WVR • Note bulk of construction complete in spite of winter

12. Budget Overview CARMA Capital Construction • 2001 – CARMA construction estimated at $15M • BIMA universities, Caltech, NSF - $5M each • Nov 2005 – NSF capital construction tasks complete • short-term funding requested for salaries of staff required to complete systems integration CARMA Operations & Development – a distributed effort • Cedar Flat – operations & outside observer support • OVRO – hardware and software maintenance and support, receiver, correlator & software development • RAL - hardware maintenance and support, receiver, correlator & WVR development • UIUC – WVR development, development and maintenance of archive and pipeline imaging capability • UMd – software maintenance and support, software development • Increased overall costs

13. Future • Largely John Carpenter’s but I will add a slide from John Carlstrom with U Chicago role + science enabled

14. Backups

15. Current Graduate Students • Berkeley • Adam Leroy, Jonathan Swift, Evan Levine, Kristen Shapiro, Nia Imara • Caltech • Joanna Brown, Micol Christopher, Stuartt Corder, Melissa Enoch, Laura Hainline • Illinois • Paulo Cortes, Douglas Friedel, Sheryl Kuo, Woojin Kwon, Jerry Shaw, Shiya Wang • Maryland • Nicholas Chapman, Rahul Shetty, Misty Lavigne, Stephanie Zonak, Elyse Casper, Lisa Wei • Chicago (SZA) • Chris Greer, Ryan Hennessy, Michael Loh, Matthew Kyle Sharp

16. First Light Enhancements • Better Site • higher elevation, atmospheric transmission x 2 improvement • improved phase stability • year-round observing: routinely at 1 mm • Hybrid array • greater number of telescopes & baselines • increased mm-wave imaging fidelity & dynamic range • increased imaging speed – snapshot & mosaicing capabilities • wide field mm-wave imaging on scales from 0.13 to 1 • (with 8 x 3.5 m U Chicago SZA array to 3) • Combined resources of partner universities • broad science and technology base
