Possible Ram Pressure Stripping in UGC 02665

• by williamaskew

  The Perseus Cluster is a perfect environment for Ram Pressure Stripping to take place. UGC 02665's umbrella shape is Indicative that RPS is occuring.

  I only found one paper that mentioned UGC 02665.

  Here is an explaination of RPS

  Thanks Abe for posting these. Top images are SDSS. the B&W image is DSS2 (blue) showing the bowed shape of UGC 02665 as it plows through the 'intra-cluster medium'

  I might have actually seen something like this. I'll keep an eye out for them.

  I smell a new project and will soon start looking for more examples 😃.

  How about this one, Billy?

  PS This galaxy is not in a cluster.

  Could this be one?

  Here is a nice article - including a video - about ram pressure stripping:

  Here is another galaxy with ram pressure stripping.

  

  

  AGZ00022ma - #NGC 4402 ; #UGC 7528

  Right in the middle of the Virgo cluster: http://apod.nasa.gov/apod/ap080425.html

  I had a look in the vicinity
  tjitso but there isnt a cluster for your object to be interacting with.

  Yeah, I checked it later and saw the same. Oh well 😃

  Just came across this one again:

  Searching for #cluster, provides with a couple of possible RPS candidates:

  Very faint:

  That first one has a good shape. Remember to check to see if redshifts of neighbouring 'cluster' galaxies are close

  Abe that is the one I thought was RPS in your 'irregular' discussion a couple months back.

  Posted March 21, 2015 8:00 AM

• by Alpha_Aurigae

  Yes, you showed us the way already then 😃

  Glad you are back 😃

  Will do.

  Maybe this one, if the features aren't the result of a merger or flyby. And it is in a cluster 😃

  We have to be a bit careful, some features may not be attributable to ram pressure stripping but the result of a fly by or a merger:
