ALMA-IMF Kinematics Telecon - June 16, 2020
Attendees: Amy, AG, GB, HL, LM, KM, SB, PS, ++ many more
Not attending: Fred, Antoine
---> 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
---> Any other business (AOB)? What am I missing?
DCO+ DCN, N2D+
HNC ?? Do we have? No sure its in? HL: Not included...
13CS --> rotation features in cores.
SiO, SO --> get them shocks!
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!!
GB + AS + HL to start analyzing these for assessment.
