      KEK in Deep Autumn Color

      In the fall, the tree leaves around the High Energy Accelerator Research Organization (Kō Enerugī Kasokuki Kenkyū Kikō or KEK) campus are becoming ablaze with autumn colors and streets are gradually covered by fallen leaves. Warm days continue into November in the Tsukuba area, where KEK/J-PARC is located.

      CASPAR: Studying the Stars from a Mile Underground

      We all have our origin in the stars. The atoms that make up the Earth, the mountains, the oceans, and our human bodies were forged in the hearts of stars. In a very real way, we are connected to the universe through the lineage of our elements. The investigation of that lineage is nuclear astrophysics, the field of study for the Compact Accelerator System for Performing Astrophysical Research (CASPAR) project.

      Why Do Fundamental Research?

      Fundamental research is typically interested in exploring ideas on the very edge of human knowledge, attempting to broaden our understanding of the basic principles of matter and the universe so that we can develop new models that allow us to fathom undiscovered depths. There’s no predetermined application in mind for fundamental research, and so sometimes it can be referred to as blue-sky research.  I like that term because I can imagine a researcher staring up into the clear, blue sky, pondering the universe and waiting for inspiration to strike.  It struck Newton in the form of an apple.  It struck the dinosaurs in the form of an asteroid.  (But that’s not relevant to this discussion).

      A Day in the Life of a Subterranean Astronaut

      As a particle physicist, I work in a unique environment: a mile underground.  I’m an Experiment Support Scientist with the Sanford Underground Research Facility (SURF), which means I support the various experiments we have throughout our entire underground campus.  As a scientist, I have a distinctive job because I don’t work on just one project, but rather on many projects helping out where I am needed.  The job can be busy, sometimes overwhelming, but it’s never boring.  Follow me through a typical day working underground at SURF.

      At a friend’s birthday party this week I met a man whose opening conversational gambit – without knowing anything about my background – was a lengthy discourse on his theory of the equivalence of atomic and solar system dynamics, with electrons orbiting nuclei just as planets orbit stars... In this case, however, his immediate response was to inform me that if only I had studied the field I would understand the truth and profundity of his theory.

      Cosmic Microwave Whatnow?

      For the last 20 years, I’ve been developing pictures of the Big Bang.

      The photons created in the Big Bang have been stretched by the expansion of space and now form a faint radiation field we call the Cosmic (since it is omnipresent) Microwave (since its intensity peaks at microwave frequencies) Background (since it comes from behind all astrophysical sources). It was accidentally discovered using a huge radio telescope, and indeed about a percent of the noise you can hear between FM radio stations is this echo of the Big Bang.

      Quo Vadis, High Energy Physics?

      High Energy Physics finds itself at a crossroads, a fact commonly recognized within the scientific community. Paradoxically, the main reason for this state of affairs is none other than the extreme success of both our theoretical framework and our experimental programs. Indeed, our current understanding of elementary particles, as encapsulated by the Standard Model, has so far been confirmed with exquisite precision by countless experiments. Even then, there are still enough urgent fundamental questions that are so far left unanswered

      Exploring the Cosmic Frontier

      In my last post, I talked about the international Large Synoptic Survey Telescope project and the genesis of Brookhaven’s participation in it. We’re now playing a major role in developing the digital “film” that will capture the most detailed images ever of the southern sky when LSST comes online in the early 2020s. We are all really excited for that day, but as scientists typically do, we’ve already started asking, “what's next after LSST?”

      Mapping the Cosmic Frontier

      First came the talks. It was the year 2000, and scientist after scientist stood on the stage in Berkner Hall at Brookhaven National Laboratory and told us that something strange was happening to the universe. Supernova explosions from as long as seven billion years ago were not as bright as they should be. Giant sheets and filaments of dark matter were being mapped, and they did not form the structures they should.

      Life’s a beach

      You work hard as a student and as a postdoc. You stumble into a great faculty job, where your university supports you, and you get to pick what you work on. As an added sweetener, that place of employment is a short drive from some lovely beaches, has gorgeous weather (the epic floods of 2016 notwithstanding) and is incredibly affordable. Sounds great right? That’s where I’ve found myself, Australia, and it’s really not what I had on my radar five or six years ago when I was frantically hoping to get a position to keep my research adventures in high-energy physics going. But here I am. With all good jobs in high energy physics research there comes a price.
