Scientists find rare dwarf satellite galaxy candidates in Dark Energy Survey data

These two images allow you to see how scientists spot dwarf galaxy candidates in the Dark Energy Camera's images. The first image is a snapshot of DES J0335.6-5403. It is the most likely of the newly discovered candidates to be a galaxy, according to DES scientists. The second image shows the detectable stars that likely belong to this object, with all other visible matter blacked out. Image: Fermilab/Dark Energy Survey

Scientists on two continents have independently discovered a set of celestial objects that seem to belong to the rare category of dwarf satellite galaxies orbiting our home galaxy, the Milky Way.

Dwarf galaxies are the smallest known galaxies, and they could hold the key to understanding dark matter and the process by which larger galaxies form.

A team of researchers with the Dark Energy Survey, headquartered at the U.S. Department of Energy's Fermi National Accelerator Laboratory, and an independent group from the University of Cambridge jointly announced their findings today. Both teams used data taken during the first year of the Dark Energy Survey, all of which is publicly available, to carry out their analysis.

"The large dark matter content of Milky Way satellite galaxies makes this a significant result for both astronomy and physics," said Alex Drlica-Wagner of Fermilab, one of the leaders of the Dark Energy Survey analysis.

Satellite galaxies are small celestial objects that orbit larger galaxies, such as our own Milky Way. Dwarf galaxies can be found with fewer than 100 stars and are remarkably faint and difficult to spot. (By contrast, the Milky Way, an average-sized galaxy, contains billions of stars.)

These newly discovered objects are a billion times dimmer than the Milky Way and a million times less massive. The closest of them is about 100,000 light-years away.

"The discovery of so many satellites in such a small area of the sky was completely unexpected," said Cambridge's Institute of Astronomy's Sergey Koposov, the Cambridge study's lead author. "I could not believe my eyes."

Mira supercomputer propels high-intensity beam science

From HPC Wire, March 6, 2015

As CERN's Large Hadron Collider (LHC) prepares to restart this March, a team of Fermilab physicists are using powerful Department of Energy supercomputing resources to reduce the risks and costs associated with producing these high intensity particle beams.

Led by Fermilab physicist James Amundson, the team is working with the Argonne Leadership Computing Facility (ALCF) to port and optimize Synergia, the accelerator simulation software package developed at Fermilab, to run on ALCF's Mira supercomputer. The hybrid Python code harnessed 100,000 cores on Mira, enabling researchers to simulate complex internal accelerator interactions. The team is especially interested in studying the effects that accelerator components exert on particles inside high-intensity, low-energy machines.

Making the case

Tim Meyer

Last week was marked by two important milestones — maybe more if you include my daughter's success at delivering one (and only one) spoonful of yogurt from bowl to mouth all by herself.

Some of you may have already met John Myer, who joins us as Fermilab's new general counsel. John takes the reins from Gary Leonard, who has served the lab for many years. Please join me in welcoming John and thanking Gary for his sincere commitment to Fermilab's success.

John Myer

John comes to us from Ingersoll Rand/Trane, where he was leader of the company's Global Center of Excellence for Government Contracts. John was lead counsel for all aspects of federal contracting and compliance and has 15 years of experience in government contracting, commercial litigation, and drafting and negotiating complex prime and subcontracts, including construction projects. Not only will John lead the legal department, but he will also provide key advice to lab leadership as we navigate the path to hosting an international science facility for long-baseline neutrino experiments.

The other key milestone last week was Fermilab's presentation of its strategic plan and FY2017 budget considerations to DOE's Office of High Energy Physics. In an all-day meeting at the DOE Germantown, Maryland, offices, the Fermilab team presented an outlook to 2020 for the six strategic themes developed over the course of the year and identified what would be required in FY2017 to advance toward those goals. The talks were kept at a high level and focused on strategies, Fermilab's core and unique capabilities and potential trade-offs.

The budget briefing was judged a success on several counts. First, in spite of a massive snowstorm barreling down on Washington, DC, that closed the city the next morning, all of the participants were present and engaged throughout the full eight-hour marathon session. Second, the DOE program managers each had a chance to learn about and discuss broader and different aspects of the Fermilab program. Third, there was substantial subsequent discussion about how best to plan for and support the primary and preponderant role that Fermilab plays in executing the P5 vision. Last and not least, the Fermilab team delivered a clear and consistent message about focused priorities and a commitment to excellence. (We are collecting the materials on an Indico website that soon will be available for viewing.)

The FY2017 briefings came together during an intense push throughout the month of February; collectively, it took more than 500 hours of effort. We would not have been successful without the leadership, patience and guidance of my co-convener, Fermilab CFO Cindy Conger. Hats off to Cindy, her team and the rest of our colleagues for successful preparation and presentation of Fermilab's vision to DOE!
