by Kyle Story Last December, I travelled to the southernmost tip of the Earth to install a new camera on the South Pole Telescope (following a rich tradition of other KIPAC researchers who have travelled to Antarctica and returned to write about it, e.g. Val Monticue and Albert Wandui). This blogpost brings you along for a bit of that journey! The author working... Read More

By Kelly Stifter The author (l) at work in the LZ lab with UMASS student Chris Nedlik. (Credit: Steffan Luitz.) Ever wanted to learn about dark matter—the elusive particle that holds galaxies and galaxy clusters together? What about dark energy—the mysterious force that is causing our universe to expand at a continually increasing rate? If so, you’re in luck!... Read More

By Dr. Richard Anantua The high-energy universe is a fascinating place to observe: giant stars explode into supernovae, briefly outshining their own galaxies; pulsars with more mass than our Sun but only twelve miles across spin hundreds of times each second; and supermassive black holes at the centers of galaxies can suck dust and gas into accretion disks and ...

by Lori Ann White The universe is full of mysteries that merit an exclamation or two of wonder and delight. Black holes, supernova explosions, planets around other stars, the thought that most of the matter surrounding us is some kind of stuff that we can’t detect—these are just a few of the cosmic marvels that warrant a “Wow!” or a “Neat!” or a “Gee whiz!” Or even...

By Harry Desmond The acronym ΛCDM (Lambda-cold dark matter) is shorthand for our current best cosmological model describing the early beginnings, evolution until now, and future development of our entire Universe. It posits a cosmos dominated by a cosmological constant (denoted by Λ, the Greek letter capital lambda) our best guess for the phenomenon of dark energy... Read More
    Dear KIPACers,   We are already well into another great academic year for KIPAC. With this latest Newsletter we want to give you an overview of the comings and goings, alert you to upcoming events and opportunities, let you know about upcoming courses -- and more. Please also have a look at the longer news story at the end, by Steve Allen and others; it... Read More
Brett Harvey explains his research to Pat Burchat.
by Lori Ann White Some things just go together. Hot dogs and mustard, smart phones and selfies, school and summer vacation. But science is a year-round proposition, and several undergrads didn't seem to mind forgoing their summer vacations to pursue a variety of research opportunities with members of KIPAC. (Protip: it’s never too soon to start thinking about next... Read More
Do you have a question about Particle Astrophysics, Astronomy, or Cosmology? Have a look through the previous questions which we've been asked and if you can't find find your answer, ask us! Ask an Astrophysicist Question If the correlation between pressure-temperature means that water boils at a lower temperature as pressure decreases, then, turns to gas as it is... Read More
Gravitational lens SPD.81
by Warren Morningstar By modeling the warped images of a gravitational lens observed with one of the most powerful telescopes in the world, KIPAC scientists have made the dramatic discovery that there is a clump of dark matter with no currently visible normal-matter counterpart in a far-away galaxy. Such unaccompanied clumps are incredibly difficult to detect and... Read More
Gravity waves from black hole collision
  By Nicola Omodei and Giacomo Vianello The first direct detection in 2015 of a gravitational wave event (GW) by the recently upgraded Laser Interferometer Gravitational-Wave Observatory, known as Advanced LIGO, ushered in with a mighty bang a completely new era in astronomy. The first science run (‘O1’) with the Advanced LIGO detector started in September 2015,... Read More
