meeting 2024 01 17 n57 - JacobPilawa/TriaxSchwarzschild_wiki_5 GitHub Wiki
- Finalizing some of the questions from last time regaring N57 and the environmental diagnostics.
-
Chung-Pei had asked about my environmental diagnostics for N6086, the BCG of Abell 2162, which were quite for the cluster.
-
I think there are a few reasons for this:
- First, I think that this specific cluster is actually not that rich. I've found a couple of other works which looked at the environment for A2162:
- Here's the BH measurement paper, which states that A2162 is a relatively small cluster with richness of 0 based on 37 members within m3 and m3+2
- Abell+1989 confirms that this has a richness of 0
- McGee+2013 studied the environment of N6086, and finds that the 4th nearest neighbor of N6086 is at a distance of 5.74 Mpc, which is roughly what I am finding (~3.5 Mpc)
- Perez-Hernandez+22 is a more updated study of the BCG, which again says it is in a relativley poor cluster especially for cD galaxies, and presents the photometry and kinematics of this BCG.
- Additionally, this is the furthest galaxy (~136 Mpc) in the sample of galaxies with large black holes included in our environmental calculation. McGee+2013 mentions above that this galaxy in particular is likely impacted by the completeness of 2MASS Redshift Survey catalog, which is only complete to the cz < 10,000 km/s, and we're right on the boundary with several of the nearby galaxies.
- I also did a sanity check on the live 2MASS online query, presented here for completeness.
- First, I think that this specific cluster is actually not that rich. I've found a couple of other works which looked at the environment for A2162:
-
I also re-ran all my environmental calculations from the catalogs that Melanie used (with no cuts on the catalog rather than the M_K < -23.0 and D < 150 Mpc as presented in MASSIVE IV, and the results of the nearest neighbor searches do not appreciably change. I've got some plots below for that.
-
All in all, I'm not sure that A2162 is as rich of a cluster as we might have thought, and I think my environmental calculations are in general agreement with the other published works above. If we're concerned about this galaxy in particular, I think we'd be fine to remove it from our plot since it's right at the boundary of the MASSIVE Survey volume, but I rather confident that my environmental calculations are correct provided the 2MRS catalogs.
- In the last meeting, we talked about using the 2MASS redshifts for all the distances, rather than relying on the HDC/LDC/redshift in that order. I've recomputed these numbers, and there were only minor changes to the environmental diagnostics.
- Here's what I'm doing in the calculations below:
-
Last time, we were looking at the environmental calculations assuming that the dSV distance (black hole measurement distance) was the truth, and I was correcting the distances for the neighbor galaxy by the ratio of (black hole measurement distance/previous "best" distance estimate).
-
We decided last time that we shouldn't use the previous "best" distance measurement (which had been HDC > LDC > Z, in that order), and instead use the redshift distances for all galaxies.
-
The numbers below are thus the result of:
-
- Compute/obtain neighbors in the same way Melanie did in MASSSIVE VII, by using the HDC > LDC > Z in that order.
-
- Replace the galaxy's HDC > LDC > Z distance with the distance presented in the black hole measurement paper.
-
- Correct the neighbor distances by the ratio of (black hole measurement distance / redshift distance dZ).
-
-
This essentially treats the black hole measurement as the truth, and makes no reference to the distances in HDC/LDC, aside from the initial step of assigning the 10 nearest neighbors. This has the benefits of preserving the groups found in Crook+2007/MASSIVE VII, but using more unique distance measurements from the redshift measurements, rather than flattening the galaxies to the same distance which are in the same groups.

- Below, I've placed the upated environment plot and the comparsion between what we were looking at last time (corrected to the HDC/LDC/Z distances), vs. this week, where I'm doing to the correction relative to the redshift distances.

- Lastly, I've also created equivalent environemtnal plots using the number of galaxies in HDC/LDC. These are roughly consistent with the plot above, with the important caveat that LDC does not contain NGC6086, and the HDC lacks N57 and N6086.

We also discussed last week exploring the prior we are imposing on Tmaj. I'm still having a bit of trouble getting this to run properly, but here are some quick results using a subset of the total model points (simply to get my dynesty to run faster for some plots for the meeting).
-
It seems like using a strict Gaussian prior with mean = 0.55 and standard deviation = scale, we can really only get a "Gaussian" posterior for small scales. As we approach such a wide Gaussian, I think we more are less recovering what we get for the uniform prior case.
- I think sticking with the scale = 0.1 case is fine, so long as we report something like the ~3 sigma uncertainty on Tmaj?
| case | no truncation | truncation |

Here are the same sets of posteriors but plotted in our fancy way

 |

We also wanted to see what the covariance between (upq) and the mass parameters are, so I've regenerated the plots above but showing these 2D posteriors rather than the Ts/mass parameters. I only included a few of the cases here since the high scale results are more or less all the same.
