Our FAST spectra for this guy is beautiful, with a nice H alpha line. Me thinks we have a #YSO 😃
what a beautiful galaxy!
Since the stuff to the left is so bright and is "bleeding into" the stuff in the circle, we usually throw these guys out.
hi lineman36,I'm guessing the "mess" you are referring to is background noise in the images
(oh and stars, which is what this guy probably is, peak somewhere in the visible )
Hi @artman40, hard to tell from the images for sure, but if you look at the SED it tells you exactly that (for a limited # of wavelengths)
looks pretty asymmetric in DSS2, ooks like a case of multiple objects to me. Also beware of SIMBAD 😃
Woah. This could be a calibration issue, lets say #imageissues for now
The images don't look too bad on this one , DSS2 IR background is a bit bright, but I bet it can still be classified 😃
hmm, odd, would have expected left object to be in WISE4 too. Otherwise central object fits criteria for #goodcandidate
possibly, that would be my guess too...
oops, that should be #trail
Nice find, looks like a meteor indeed, possibly a satellite , #trails!
It looks like they aren't contaminating the centered source too much, so I think it could be good
good find, a possible #imageissues
let's give this an #imageissues tag, so we can track these problems easily later on
Hmm, maybe we should start hashtagging these, #imageissues ?
we have run across a few of these now in the SDSS images, more info to come...
hmm, weird! probably an #artifact , contamination from scanning the DSS2 plates perhaps?
very true, but getting honest answers/classifications helps us refine our search in the future.
yikes, perhaps an EVILcandidate?
hmm, super compact in SDSS is a bit odd, & according to SIMBAD it is a quasar, but technically it meets our criteria for good, so yeah!
Woah, extreme #trails I'd say
tough call, I'd probably still call it a #goodcandidate it looks like the second source you're worried about fades out before the WISE bands
adorable! You could also mark this one as a clear #multipleobjects
Looks pretty good, a little out of circle in WISE 4 , but that somewhat normal for bright sources. Feel free to use hashtag #goodcandidate
2nd object looks consistent with noise in 2MASS K, I'd probably classify this guy as a galaxy
that's a fair call, looks pretty not round in the DSS2 image
looks pretty good, feel free to add a #goodcandidate as you find
looks pretty good to me, something odd going on SDSS Z band, image, but otherwise fits the bill
It's not within the circle, so it should not be contaminating the SED or anything. I'd say #goodcandidate
maybe we should start the hashtag "prettyspirals", this is one of the loveliest so far I've seen
@w80salmon yep, the object was so bright it created those artifacts in the images, called "diffraction spikes"
I'd say so, but we like to keep track of these ambiguous objects too
It is in the circle, but it doesn't look like it would contaminate the SED of the central object too much... close call!
but definitely looks like #multipleobjects 😃
Its hard to tell whether its an actual binary, it could be a background object like a faint galaxy
Yep, not everything exists will come up as a SIMBAD object because we are seeing things that aren't in that database. Exciting, right?
Oh boy, that is odd. It could be a problem with how we scaled the image fluxes More to come...
@gabrielapetrie a disk around a young star won't look disk-shaped in these images, those will be round (ish). Hope that helps!
@gabrielapetrie, this may be a "birds-eye-view" of a galaxy
@gabrielapetrie , galactic disks indeed look like this.
I think you are probably right, it looks both asymmetric and a bit oval at shorter wavelengths
it looks like a single object to me, it is shifting frames a little bit which is maybe what makes in look like a double
I agree with you, feel free to hashtag it as #galaxy
hmm, the distance to center SIMBAD is listing is pretty large though.
@dtolman, it looks like a #goodcandidate to me, like @debastroc said, the trails are probably just satellites
