hi, i am trying to get Cloudy to output (punch) data which will allow me to make a plot of how the ionization states of a few ions varies with radius - the...
Hi Eric, At the AAS meeting you mentioned that turbulence can be an important source of heating and indeed Clump 1 and Clump 2 in the Inner Galaxy are highly...
Hi Everett, I would be happy to help you set up a model. We talked about a lot of different things at AAS including turbulence but you should check with the...
hi! I have a problem with N4 line 1486A. This is a doublet 1485+1486 actually. If I check the lines intensities and ratios in the main output .out they are...
Hi Anna, this is indeed a bug. To fix it change lines 662 & 663 of prt_lines_lv1_li_ne.cpp from linadd(embesq.em1486,1485,"N 4",'i', " the N 4] slow...
... Hi Peter and Christophe, I apologize if I write only now in the discussion board!!! I use this "dense_fabden.cpp" that I wrote below; in that file I wrote ...
Hi Yago, yes, this result makes sense. Collisions between gas and grains will tend to bring the temperatures of the two together. If you do a simulation that...
Hi Yafo, I completely agree with Gary's response. The first question you have to ask is whether the presence of grains in a 10 MK plasma is realistic. What is...
Hello there, I was wondering if there's an easy way to simulate a plasma of a given density that is in LTE at a single given temperature (not externally...
Hi Linda, Yes, indeed. The simplest way to do this would be something like the following: hden 4 coronal 4 init "honly.ini" stop zone 1 The ³coronal²...
Hi, First of all, thank you very much for your explanations. I must confess I was not originally interested in such a hot gas, but I think this result, if...
Hi there, One empirical way to see if grains are present is to look for gas-phase depletions. In the galactic ISM elements like Ca, Al, and Fe are strongly...
Hi Linda, My response was less than helpful for a few reasons. Firstly, my example doesn¹t come close to reaching LTE. Secondly, I didn¹t even address your...
Hi Ryan, Thanks for your replies! I tried your first suggestion this morning and was slowly coming to the conclusion that I wasn't in LTE, so thanks for...
Hi Eric, I have been searching for observed turbulent velocities, but have been unable to find any. I believe they are difficult to estimate because the...
Hi Linda, Yes, you could lower the density, add whatever SED you like, and increase the ionization parameter until you have enough photons to achieve LTE at ...
Hi Everet, The turbulent velocities should be in km/s but the constants in the equations I mentioned before convert the heating to to cgs units. Maybe now...
Hi Yago, ... The question remains what heats the gas to 10 MK. I am not an expert on intra-cluster gas, but shocks would be a likely explanation I would ...
Hi, I am trying to reproduce graphs of EW in the phi(H) n(H) plane, as shown in Baldwin et. al (1995) and Korista & Goad (2000). However, I am confused about...
Hi all, when I put the grain in the simulation of a PN and I use "stop temperature off" and "stop mass 34.1" (beacause I would reproduce the emission of the...
Hi Patrizia, Thanks for the report! I could reproduce the problem. The basic problem is that this simulation is spherical and also goes very deep, which causes...
... The normalize command has no effects on the punch continuum output. I tried this to make sure ... you could read the EW off the main output (the relative...
Hi Ryan et al., Thanks again for the help with the STE command! I'm getting good results with that. While playing around with different values though, I...
Hi Linda, If you add the COSMIC RAYS BACKGROUND command, the problem goes away. This is in general advisable when modeling cold molecular gas. The trace ...
Hi, ... That is not entirely correct since the "Inci" 1215 entry you normalize by will be lambda*F_lambda, so you need to multiply the relative intensity in...
I'm playing around with a toy model AGN BLR (input below), and on the advice of Gary Ferland I'm looking at the inward component of the emission lines. The...
Hi again, I'd like to ask another question... I was wondering if it's possible to change the maximum frequency that is output by the "punch total opacity" or...
