Public outreach

Not all scientists talk like Sheldon from “The Big Bang Theory”. Well, we sometimes do, but not always. Below are links to news articles which explain for the greater public some of the science results I have contributed to over the years. If you’d like to learn more about astronomy in general, please check out the Astronomy Series on my personal blog!

The first view of the brightest galaxy cluster using high-resolution X-ray spectroscopy

hitomi_perseus_cluster_600

The micro-calorimeter array onboard JAXA’s Hitomi satellite was, briefly, the coldest object in space, cooled with liquid helium down to 0.05 degrees above absolute zero. This made it possible to record the best X-ray spectrum ever obtained from a cluster of galaxies.

Glow from the Big Bang Allows Discovery of Distant Black Hole Jet

b30727

A surprise discovery of an X-ray bright jet from a very distant supermassive black hole is featured in this press release from February 2016. This finding shows that black holes with powerful jets may be more common than previously thought in the first few billion years after the Big Bang.

The chemical requirements for life are common throughout the cosmos

A Suzaku survey of hot, X-ray emitting gas in the Virgo galaxy cluster shows that the elements needed to make stars, planets and people were evenly distributed across millions of light-years early in cosmic history, more than 10 billion years ago in this press release from October 2015.

Birth of a radio phoenix

This press release from August 2015 shows evidence for a faded electron cloud “coming back to life,” much like the mythical phoenix, after two galaxy clusters collided.

Serial black hole eruptions

A Chandra image release from June 2015 showing how multiple eruptions from a supermassive black hole over 50 million years have rearranged the cosmic landscape at the center of a group of galaxies.
