BRC Spring work

Big Picture

We need to come up with a short list of papers to read in detail and discuss. We'll rotate through our short list of papers, and each of you will get one to present to the group. This is modelling a so-called "journal club", a common occurrence in astronomy departments/groups/centers, where the papers are usually selected out of recent astro-ph mailings.

Papers to discuss

Type in your paper suggestions here....

Luisa nominates - either this one (IC2118, from my original teacher team), or the one I am in the process of finishing writing on CG4 from my team last year. The reason for this is because the analysis we will do for our BRCs is very similar to the analysis we did for IC2118 or CG4.

Chelen's nominees - reading the IC2118 and/or the CG4 paper would be good ways to learn the analysis procedure we're going to use/modify/manipulate. I also think a couple of papers on BRCs would be helpful for background information. Here's the bibliography from our proposal (with my comments) --CJohnson 09:55, 23 March 2011 (PDT)

paper	Chelen's notes	Luisa's notes	presenter/ present with
Guieu, S., et al., 2010, ApJ, 720, 46 (pdf)		the 2118 papers.... because our work will look a lot like this	TO BE DISCUSSED 3/30, MARCELLA TO LEAD
Ogura K., Sugitani K., Pickles A., 2002, AJ, 123, 2597.	Optical + 2MASS; contains general info of BRCs	Most recent of the Sugitani series of four. Using Halpha to look for YSOs, following up their other work. relevant issues: using multiple wavelengths to find YSOs (see Finding cluster members), spatial resolution (see Resolution), caveats with finding candidates. Nice intro, summary of larger issues, discussion of results. Need to be sure that this catalog is included in our list of previously known YSOs in this region, compare our results to theirs. Finding charts helpfully included so we can match obj. ***Discuss this one. Maybe not the other Sugitanis, but if we do discuss the other Sugitanis ("Group S") then they should be combined here.	do this, possibly with rest of group S
Sugitani K., Fukui Y., Ogura K., 1991, ApJS, 77, 59.	SFO article to which many other articles refer ... might be worth a review??	the original SFO, origin of "BRC" terminology, numbers 1-44. covers the northern hemisphere. has nice intro/summary of what's going on in BRCs, CGs, etc. Nice approach of combining two large surveys -- POSS and IRAS; nice clear discussion of weed-down process. Second half of paper (detailed analysis of IRAS colors, etc.) obsolete but has same essence as what we do now. If we do this one, recommend review with other Sugitani, Ogura papers.	drop? else w/ group S
Sugitani K., Ogura K., 1994, ApJS, 92, 163.	another survey	SFO/BRC catalog/nomenclature continued into the southern hemisphere. (NB: all our obj are in the N. Hem paper!). SFO/BRC numbers 45-89. Second in the Sugitani series. Again, much of detailed analysis now obsolete. If we do this one, recommend review with other Sugitani, Ogura papers.	drop? else w/ group S
Sugitani K., Tamura M., Ogura K., 1995, ApJ, 455, L39.	IRAS survey	JHK follow-up of IRAS sources from SFO. relevant issues: using multiple wavelengths to find YSOs (see Finding cluster members), spatial resolution (see Resolution). Shame on them for not publishing a data table or even a figure with the locations of everything they identify as a YSO! BRC 27 is one that they choose to include in a finder chart, but doesn't do us much good. Nice summary of larger issues, timescales. Short paper. If we do this one, recommend review with other Sugitani, Ogura papers.	drop? else w/ group S
Chauhan N, Pandey A.K., Ogura K., Ojha D.K., Bhatt B.C., Ghosh S.K., Rawat P.S., 2009, MNRAS, 396, 964.	Tests S4F theory; survey using Spitzer archival data; not deep enough??	yes, this one we should spend some time on
Gregorio-Hetem J., Montmerle T., Rodrigues C. V., Marciotto E., Preibisch T., Zinnecker H., 2009, A&A, 2009, 506, 711.	X-ray survey of CMa region	BRC 27. ROSAT+VRI data. relevant issues: using multiple wavelengths to find YSOs (see Finding cluster members), spatial resolution (see Resolution). We need to include this catalog in what we accumulate, and compare our results to theirs.
Morgan L. K., Urquhart J. S., Thompson M. A., 2009, MNRAS, 400, 1726.	Radio, mid-ir, SCUBA observations; redefined SFO catalog	three morgan papers can probably be discussed in the same week
Morgan L. K., Thompson M. A., Urquhart J. S., White G. J., 2008, A&A, 477, 557.	SCUBA survey
Morgan L. K., Thompson M. A., Urquhart J. S., White G. J., Mio J., 2004, A&A, 426, 535.	Radio and mid-ir survey
Shevchenko V. S., Ezhkova O. V., Ibrahimov M. A., van den Ancker M. E., Tjin A, Djie H. R. E., 1999, MNRAS, 310, 210.	Optical catalog that includes both BRC 27 and BRC 34; contains general info on BRCs
Soares J.B., Bica E., 2003, A&A, 404, 217.	2MASS + optical survey
Soares J.B., Bica E., 2002, A&A, 388, 172.	2MASS obs of BRC 27

Wiramihardja S.D., Kogure T., Nakano M., Yoshida S., 1986, PASJ, 38, 395.	Optical survey of CMa region
Rebull, L., et al., 2011, AJ, submitted (CG4 paper)	do as last review before we get started on ours?		do last?
Allen L., et al. 2011, American Astronomical Society, BAAS, 43, 258.15.	Poster from AAS ... good to review?	ok, but not a lot of content beyond the images and their 'big picture' work.	skip?
Makovoz D., Marleau F. R., 2005, PASP, 117, 1113.	MOPEX info	VERY technical, not a manual, and not all that terribly relevant to what we're doing. let's drop this one from the list.	(drop)

I second reading all of the bibliographic articles, plus the one on IC2118. My reasoning is that I think we should be familiar with all of the work for the references we cited, and I would like any preview of the work that we will do. The older articles I have been looking (Stromgren, 1948 & Sharpless 1959)at are interesting for their historical context, but probably not necessary for all of us to read. --Sartore 12:34, 23 March 2011 (PDT)
