LIGO GRAVITATIONAL WAVE (GW) EVENT GW190521

Five years ago, LIGO announced the first ever detection of gravitational waves which were best explained by the merging of two stellar-mass black holes. On May 21, 2019, both LIGO and VIRGO detectors picked up a very short gravitational wave event, GW190521. This event is from the most massive binary black hole merger observed to date. 

PAPER II: (ANOTHER) NEW GAMMA-RAY SNR

In 2006, very high energy ( >2 TeV!) gamma-ray emission was discovered to be located right next to a middle-aged supernova remnant but, no one knew how they might be related. Then, a decade later, we found more gamma-ray emission that extended to energies in the Fermi range and localized the emission on the western edge of the same remnant.

In blue is soft (or low energy) X-ray emission, surrounding it in red is infrared emission. The gamma-ray source is discovered to coincide with the red filament to the west (right) in the image (taken from Combi+2010 and is cited in the post directly).

CLEMSON, SOUTH CAROLINA (Chapter 2)

Four years ago, I moved away from home for the first time right after graduating from college. My first year in graduate school was tough. I struggled with the workload which for me included mental health issues and a lack of confidence. Sometimes blooming into the person you want to be takes time.

SAFE WAYS TO ENJOY LIFE DURING A GLOBAL PANDEMIC

Another world is not only possible, she is on her way. On a quiet day, I can hear her breathing. Coping with life during a global pandemic and consequent quarantine is no easy task and I share some ideas that have helped me that may help you, too. I remind you to check in with yourself every now and then. In time, I hope we learn to be humble and mindful of our actions and their impacts on others as we navigate this new world together. 

SIX AMAZING FEMALE ASTROPHYSICISTS YOU SHOULD KNOW

We applaud these women for their courage, knowledge, and wit that it took for them to accomplish their goals in spite of added difficulty. 

PART VII: SENIOR YEAR

Ruining my own reputation one blog post at a time! I share my senior year memories from college. I try to be extra insightful on the graduate school application process and time and the hard reality of what it was like to get here.

SCIENCE V. RELIGION

Is science an attack on religion? Short answer: No. In fact, the two are not mutually exclusive and when embraced, can be a powerful tool for mankind.

Let’s do some reflecting.

SPECTRAL ENERGY DISTRIBUTIONS

Why do we plot spectral energy distributions (SEDs) the way we do? What does it mean to us? How does it relate to the total flux from a source at a given frequency? What are the perks to defining and plotting the spectral flux density? Let’s break down the SED convention together.

COSMIC RAY ACCELERATION IN SHOCK-CLOUD INTERACTIONS

Can we establish the Vela SNR and its shock-cloud interaction as a possible site where cosmic rays are produced? I introduce, for the first time, spectral energy distributions and their importance in determining what particles are responsible for observed gamma-ray emission and how it is related to cosmic ray (CR) acceleration.

Breaking down this spectral energy distribution (SED) in my latest blog post! In the future, I’ll discuss why we plot E^2 dN/dE (spectral flux) as opposed to just observed flux at a given energy.
