ALMA-IMF Kinematics Telecon - June 16, 2020

ALMA-IMF Kinematics Telecon - June 16, 2020



Attendees: Amy, AG, GB, HL, LM, KM, SB, PS, ++ many more
Not attending: Fred, Antoine



Agenda:

• Proposed topics for discussion:
  

---> Line wish list (first suggestions: N2H+, C18O, SiO)
---> Coordination with DR team & hot cores WG.  
---> Status of line reductions.
---> As the line DRs firm up (in process now), we aim to develop more
     concrete paper plans, science topics.  Including but not limited
     to: N2H+ & C18O kinematics as a function of evolutionary state;
     SiO shocks vs. evolutionary state.  Particular regions vs. full
     sample.
---> Any other business (AOB)?  What am I missing?

• More lines: 
  

SO, OCS, (perhaps extended emission not quite so important)
DCO+ DCN, N2D+
HNC ??  Do we have? No sure its in? HL: Not included...
13CS --> rotation features in cores.  
 SiO, SO --> get them shocks!

• DR status
  

N2H+ cubes most likely to have soon.

AS: important criteria: need extended emission in some tracers, not all.
      good to keep this in mind, not all lines require the more complex
      reductions of combining 12+7+TP.  BUt some do.  

N2H+ --> quick look cubes reduced.
         only 12 m included. reasonable shape.
     have some combined + 7m cubes, but quality not clear.

Lee --> C18O looked "blobby"
       has anyone looked at 7m?
    has anyone looked at single dish only?
        answer seems to be "No", but could we look?   

GB: what about total power.
    need to include.
    so need 12 + 7 + TP.
    AS strongly agrees w/ this point.

AG:  12+7 look bad.
     problem in the cleaning? 7 m data noisy.
     informed by continuum.
     friday at 9:00 EDT, look at data.
     if you want data, email AG to get test region.

KM: C180 + N2H+ --> quiescent cold cores. not only hot cores
    but cold cores.

HL: interested in 12m data, core scale kin, evolution.
    method to tackle complex spectral profiles of N2H+
    N2H+ line profiles are complex

AG: See NH3 fitting in context of Green Bank ammonia surveys,
see talk at ALMA-IMF meeting for example.
plenty of tools out there

LM (+ AS) --> core velocities super interesting!!

• AG: quicklook moments, etc, exist here:

• Immediate actions:  
  

AS to get an example region from AG in N2H+,
GB + AS + HL to start analyzing these for assessment.
