@astro_nolan Amazing! Congrats Nolan, I can't think of anyone more suited for such a distinction

@googlechrome + the only reason I switched from edge to chrome is to have less of a hassel having my passwords synced between my computer and my pixel

[Nasser Mohammed @nasstronomy]

I can tell no @googlechrome developers annotate PDFs because why would the highlight/markup tools appear to the right of the document? It makes side-by-side multitasking quite frustrating.

[Nasser Mohammed @nasstronomy]

@googlechrome incase its not clear, in my option the correct answer is for it to be above the document

We have a new paper out on the arXiv! https://t.co/cJFzC1UwL6

We identify 41 new spectroscopic member stars of the EMP ([Fe/H] ~ -3.3 dex) C-19 stellar stream, measure a very kinematically hot ~8 km/s velocity dispersion, and find a 'spur' feature within the stream (à la GD-1)

@sam_rosenfeld when they are wrong, but at least *they* are wrong

@sutherlandphys contrasting any city to ottawa will make you feel this way

In our new paper today (https://t.co/eIkeug3AJ7), we report a blue pearl in a cosmic shell: an ultra-compact dwarf embedded in the giant tidal debris around NGC 7531. Its radial velocity, obtained in @keckobservatory, confirms it is the nucleus of a (now) defunct dwarf galaxy.
