Artist's impression of a galaxy with strong galactic winds and an active nucleus.
An international team of researchers, most of whom have ties to KIPAC, has shown that the hot diffuse gas that fills the space between the galaxies has the same concentration of iron in all galaxy clusters that were studied in sufficient detail by the Japanese Suzaku satellite. These results confirm the team's earlier findings regarding the Perseus Cluster,... Read More
Dear KIPACers,   With this Newsletter, we review a series of exciting events and workshops that KIPAC has hosted in 2017, and welcome a new cohort of graduate students and postdocs.  We also bid adieu to those who are moving on to the next stage in their careers. See below for details. We’ve also included some dates for upcoming events, and courses of possible... Read More

by Dan Wilkins Supermassive black holes power some of the most luminous objects we see in the Universe. When material spirals into a supermassive black hole in the center of a galaxy that is in excess of a million Solar masses, it gives rise to an active galactic nucleus, or AGN (also discussed in two previous KIPAC blogposts: this one focused on observations of...

By Lori  Ann White At first glance, the Blind Analysis workshop hosted by KIPAC last month was only one of many gatherings during a very busy March (which actually started the last few days of February). On the SLAC campus, the Institute hosted the Cosmology with CMB-S4 workshop, and then, immediately began preparing to assist with the New Horizons in Inflationary... Read More

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
