The Mysterious "Pigs" Josh Peek Carl Heiles 3 to 5 cold, compact clouds at high latitude, v = -30 km/s paper in preparation TOGS, VLA follow-up, AO follow-up 
New and existing Local Group dwarfs Jana Grcevich (PhD) Mary Putman, Josh Peek, etc.? Cataloguing discrete GALFA clouds for best bets Beginning of moving beyond by eye searches All GALFA cubes, follow-up archival and deep optical 
Accretion/Cooling at the disk-halo interface Destry Saul (PhD) Mary Putman etc. (add yourself to these) Cataloguing disk-halo clouds, overall properties and morphology, link to simulations and other observations Just beginning All GALFA cubes, Halpha, absorption line obs. etc. 
Origin of Complex C Wen-Hsin (Tina) Hsu (PhD) Putman, Stanimirovic, Peek, Heitsch Comparison of the Complex C clouds to Stream Paper close to submission A2060 
HI in and near globular clusters Jacco van Loon Just let him know Search for gas in GCs and use them as probes of the Galactic Halo Previous publication and started analysis of new data GALFA cubes within a few degrees of GCs 
Foreground HI in the direction of the Virgo cluster Mary Putman Josh Peek For the Herschel survey of the Virgo Cluster Some preliminary maps have been made GALFA cubes towards Virgo 
Cold dust in the extended gas distribution of M33 Jacco van Loon anyone who wants, from the GALFA-HI and M33 Spitzer teams The final MIPS mosaics of M33 are combined with GALFA-HI maps: a preliminary look shows cold dust in some of the extended HI MIPS 70 and 160 micron maps are being combined with GALFA-HI cubes GALFA-HI cubes on M33, and Spitzer MIPS maps 
Search for shells in the GALFA surveys Eric Korpela Shauna Sallmen & some undergrads at UW-Lax A follow on to a similar thing done with SETHI Just starting TOGS, I-GALFA, all cubes eventually 
An old shell in the direction of the galactic anticenter Eric Korpela Kevin Douglas, Shauna Sallmen + undergrads Shell found in SETHI redone with ALFA+H-alpha imaging Paper drafts stalled cause Eric's swamped and Kevin can't hit him from there. A2056 
A technique for extracting structure from HI data cubes Eric Korpela  Playing with analysis techniques to separate overlapping structures Beginning phases. Seems to work half the time, but needs much refinement. Any and all. 
Cold Leo Cloud Josh Peek Carl Heiles, Dave Meyer, Katie Peek Looking at very interesting cloud in leo as an ISM laboratory  many science results on hand, nothing on paper yet a2220 and overlapping data 
HVC dust absorption limits Josh Peek Genevieve Graves Using SDSS + GALFA to put constraints on HVC dust absorption 1/2 completed DR1-S 
A search for gas in mini-haloes around M31 Josh Peek / Jana Grcevich Jana Grcevich / Josh Peek, Mary Putman Putting limits on HI content of haloes around M31 beyond the virial radius just starting DR1-S 
Putting limits on dust in the Smith cloud Jay Lockman Josh Peek Finding dust in the Smith Cloud in progress a2329 
Very compact HI clouds from GALFA-HI Ayesha Begum Nick Ballering, Snezana Stanimirovic Cataloguing and study of properties of very compact HI clouds  In progress All GALFA cubes  
MBM 53-55 Cloud Complex Steven Gibson Eric Korpela, Snezana Stanimirovic, Carl Heiles, Kevin Douglas, Josh Peek Detailed structure and atomic/molecular composition of a large "shell" that may not be data on hand, AAS poster in 2008, currently on hold TOGS, IRAS, DIRBE, various CO, Na-I absorption 
Perseus Molecular Clouds Rene Plume Lewis Knee, James Di Francesco, Kevin Douglas, Steven Gibson Atomic/molecular structure of a nearby star-forming region early GALFA PR images, delay for lack of original PI time, analysis now proceeding A2174 + COMPLETE CO 
GALFA-HI & NVSS Carl Heiles Josh Peek Using the NVSS sources to determine absorption through HI infant-like, but active! All GALFA-HI 
Reducing Fixed Pattern Noise Destry Saul / Josh Peek  Investigating Fixed Pattern Variability and "Stupid" Basketweaves as a solution. Just started Archived TOGS, and maybe new "stupid scans" 
Atomic-molecular transition in the Milky Way Min-Young Lee (Ph.D) Snezana Stanimirovic + K.Douglas + ? Compare some theoretical predictions for molecule formation to observational data using GALFA and other H2 measurements Just started Not yet specifically determined 
Cold Atomic Clouds in HI Self-Absorption Steven Gibson K.Douglas, others welcome Census of HISA features at low latitudes (1st quadrant + anticenter), comparison to other ISM tracers visual ID of many interesting features in TOGS and I-GALFA data; adaption of IGPS search algorithms to GALFA planned TOGS, I-GALFA, TOGS2 when available 
Cold Atomic Clouds in Narrow-line HI Emission Steven Gibson K. Douglas, others welcome Census of NHIE clouds, comparison to other ISM tracers visual ID of many interesting features in TOGS data; suitable algorithms for full-scale search under investigation All GALFA cubes
