ARG0002ush why the shape distortion of z 0. 029 galaxy SDSS J011924.13+122648.6 ? the radio source

• by A1001

  SDSS J011924.13+122648.6 Mrk 984 south phz 0.029 .

  SDSS J011924.59+122742.8 north phz 0. 029

  was there a flyby of the galaxies or is there gravitational action between the galaxies?

  That is a spectacular image. I'm going to add this to the overlay list.

  The shape distortion that I think your referring to is SDSS J011924.17+122656.4, which appears to be a back ground galaxy with a z_ph=0.142 ± 0.0686.

  would like to know what the blue cloud and yellow like area is?

  is it a galaxy?

  is it part of the bright center that is SDSS J011924.13+122648.6 Mrk 984 at phz 0.029 ?

  or is it the north .SDSS J011924.17+122656. at ph z 0.142 that SIMBAD says is a Infra-Red source galaxy ?

  would like to see your overlay of it

  This is a really cool system! 😃

  It's so distinctive that I'm pretty sure I've seen it before somewhere, maybe in the (now old) GZ Talk? Or perhaps even in the (very old) Galaxy Zoo Forum?

  Found it! 😃

  It's AGZ0004wvf in GZ Talk.

  north from MCG+02-04-022 SDSS J011924.59+122742.8 ph z 0. 029 z.0.04889 and

  SDSS J011924.13+122648.6 Mrk 984 south phz 0.030 z 0.04772

  was there a flyby or is there a gravitational action between the galaxies ?

  Hi:

  The galaxy pair is Arp 119 at spectroscopic z = 0.048. There's a cool paper by Hearn and Lamb (2001) who found with N body simulations that the ETG passed right through the disk of the spiral, with the two now flying apart. There are also detailed kinematic observations reported in Marziani et al. (1994) (note the second author!). The stuff protruding to the north from the disk galaxy is part of it, and not an overlap.

  Pairs like this challenge one's notions of what interacting galaxies should look like, don't they?

  It's also AGZ000d3lg in the retired GZ. Scroll down for one of the mods' comment, which nicely illustrates the point I was getting at with the last sentence of my previous post.

  Thanks for the comments mlpeck, JeanTate, and A1001.

  Here's a First contour overlay.

  

  The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
  thread. First in red.

  Host is SDSS J011924.13+122648.6, with associated radio references in NED, and an ALLWISE reference, ALLWISE J011924.12+122649.9.

  SDSS J011924.13+122648.6

  

  There's a cool paper by Hearn and Lamb (2001) who found with N body simulations that the ETG passed right through the disk of the spiral, with the two now flying apart.

  Will definitely read those papers. Very surprised.

  As for a description of the radio morphology, extended? First cut-out below.

  Cool! 😃

  It's interesting which parts of the galaxy/galaxies the FIRST radio emission comes from, and which parts it does not ...

  From a starburst as a result of the interaction?
