Deck the halls with a galaxy cluster? A team of astronomers including #NRCAstronomy’s Plaskett Fellow Madeline Marshall took a closer look at “The Christmas Tree Galaxy Cluster” using observations from @NASAWebb & @HubbleTelescope

@astroferreira @AstroMikeMerri Christmas movies and traditions make so much more sense here! So used to it being in the summer 🏖️

[Hubble @NASAHubble]

Hubble and @NASAWebb joined forces for one of the most colorful views of our universe – ever.

This is a galaxy cluster called MACS0416, located a whopping 4.3 billion light-years away: https://t.co/9JiYegbwnd

PEARLS team! Gravitationally lensed Kaiju star! This one was named Mothra because it's in an otherwise dark region of the cluster, and moths come out at night...

@WhataMergerJr \vspace, the most useful tool in astronomy

@lyAaronYung Don't feel bad about complaining, that's not your name! You should be able to have the most complicated name and still expect them to get it right. And yours is so straightforward!

Hey @NatlParkService, did somebody say Fat Bear Week? 🐻

Here’s galaxy cluster El Gordo, or “the Fat One." Containing hundreds of galaxies that existed when the universe was 6.2 billion years old, it's the most massive cluster known to exist at that time! https://t.co/hqVusGKvat

Exciting observations from @NASAWebb Telescope featured in @universetoday! #NRCAstronomy Plaskett Fellow, Madeline Marshall, is part of a team whose observations are shaking up how we think about the shapes of our galaxies: https://t.co/UV6oBJeIz4

@astroferreira The only problem with island life is how hard & expensive it is to leave the island

[Maddie Marshall @AstroMad]

@WhataMergerJr Used to dread the first few weeks of semester because the undergrads would think our office was their physics lab because of a similar naming quirk. We drew a map to stick on the door 😅

[ICRAR @ICRAR]

Awesome new images from @NASAWebb dropped this morning - but before they hit your screens, they came past ICRAR PhD student Jordan D'Silva on their journey from raw data to finished picture.

[NASA Webb Telescope @NASAWebb]

Youths!

Webb observed galaxy cluster El Gordo, a cosmic teen that existed 6.2 billion years after the big bang. The most massive cluster of its era, it’s a perfect gravitational magnifying glass, bending & distorting light from distant objects behind it: https://t.co/BrYH55h77F

@bmac_astro @aman_chokshi @SpaceTelescope @NASAWebb I think it's the usual 3:00 & 9:00 spikes that are produced by the secondary supports, the images are just rotated

[Maddie Marshall @AstroMad]

A great article about some super exciting JWST results that we've been waiting years for 🤩

[NASA Goddard @NASAGoddard]

🐻 Lions and tigers and black holes, oh my!
This #BlackHoleWeek, we’ve created a handy guide to help you determine if what you’ve found is a black bear…or a black hole.

[Maddie Marshall @AstroMad]

@shouldhaveaduck @astro_stephi, I think you would appreciate this, and also Miss Lemon needs a strawberry purse.

[William Keel @NGC3314]

(Revised+accepted) paper day! PEARLS team HST+JWST analysis of dust and gravitational lensing in @galaxyzoo galaxy pair VV 191. Redone w/updated JWST calibrations; photo-z for lensed galaxy is lower, dust reddening in spiral better constrained.

@lyAaronYung @stsci @NASA @NASAHubble @NASAWebb @NASARoman Congratulations Aaron, fantastic news!! 🥳

[Maddie Marshall @AstroMad]

@aaysaxena @janerrigby JWST spectra, the ultimate workplace hazard

[Maddie Marshall @AstroMad]

@astroferreira Thank you! I'd say that we work quickly 😉 but really this took 4 months and he just happened to advertise it with perfect timing!

[Maddie Marshall @AstroMad]

My first JWST paper is out today 🥳 We studied two quasars in the early universe (z=6.8) with the NIRSpec IFU to find black hole masses! Host Galaxies! Black hole-host mass ratios! Merging neighbouring galaxies! Outflows! So much beautiful data!!
