I successfully defended my thesis and am now Dr. Caprice Phillips (its got a nice ring to it!). So thankful for my advisors and mentors including Jackie Faherty and @ohdearz.bsky.social and friends who were here to support me. Im the 2nd Black women to get a PhD from my department. Full of joy.

In this ancient Assyrian letter, astronomers complain that they can’t do their jobs or teach astronomy β€œbecause of the ilku-duty”, a type of taxation in the form of labour.

Nonetheless, the backsplash galaxies stand out as unique. These have previously interacted with a massive galaxy which has ceased their star-formation. Although they are isolated presently, their properties are different from other field dwarfs that share their environment. πŸ”­

We study the star-formation rates and their evolution to find that the low-mass dark matter halos these galaxies are harbored in and their isolation with respect to massive galaxies, produce conditions conducive to active star-formation. πŸ”­

Dwarf Galaxies in the TNG50 Field: connecting their Star-formation Rates with their Environments The dwarf galaxies comparable to the LMC and SMC, with stellar masses $7.5 <{\rm log}(M_{\ast}/M_{\odot})<9.5$, are found in a diversity of environments and have long quenching timescales. The way thi...

Hi all, I'm glad to announce that our latest work is finally up! It's concerning the abundance of actively star-forming field galaxies comparable to the LMC and SMC (~0.1-1 billion solar masses). Using the TNG50 simulation we investigate the role that their environments play in this phenomenon. πŸ”­

ooh that's cool! there are certain calibrations to derive the galaxy properties (e.g. mass) from their apparent mag or sizes if their distances are known.

if you want to measure the structural properties of the galaxies, you might want to use SourceExtractor or Imfit.

A black and white photo of Jocelyn Bell Burnell looking at a printout in front of the large radio dish she used. She is wearing cat's-eye glasses with her brown hair pulled back. Her head is turned towards the camera and she is smiling.

The printout where Bell and Hewish noticed the regular signal associated with the pulsar.It is a green-yellow graph paper with a staticky red line showing occasional spikes. There are hand annotations labeling the spikes and recording the time and date of each one.

Jocelyn Bell Burnell transformed astronomy #OTD in 1967 when she made the first observation of a pulsar.

She and advisor Antony Hewish initially dubbed the object LGM-1 (β€œLittle Green Men”) for its regular signal, but soon identified it as a rotating, magnetized neutron star. (1/n)

The galaxu is a very oblong, blue disk that extends from left to right at an angle (from about 10 o’clock to 5 o’clock). The galaxy has a small bright core at the centre. There is a clear inner disk that has speckles of stars scattered throughout. The outer disk of the galaxy is whiteish-blue, and clumpy, like clouds in the sky.

Labeled β€œartist’s concept” at bottom right, the graphic shows a closeup of a dwarf galaxy, which appears roughly circular with a light yellow bar in the center. Faint, blue, wispy, cloud-like features surround this yellow bar, and they are sprinkled with tiny white specks. A wide, wispy, purple arc appears to the left of the galaxy. Trailing the galaxy is a large, faint, wide, tail-like feature.

The Large Magellanic Cloud (LMC) is one of the Milky Way galaxy's nearest neighbors. This dwarf galaxy looms large on the southern nighttime sky at 20 times the apparent diameter of the full Moon. And it survived a crash with our galaxy’s halo. (1/6)

We shed light on the environmental processes responsible for transforming the low surface brightness galaxies (LSBGs) by looking at their color (red vs. blue) and their surface brightness. Surprisingly we detect these processes taking place even outside the extents of the massive galaxies. πŸ”­πŸ§ͺ
