Science Highlights
Interstellar iron found hiding in plain sight
XSEDE resources used to discover new class of molecules
Iron, one of the most abundant elements in the universe, is most typically found in gaseous form in stars such as the sun and in a more condensed form in planets such as Earth.
Iron in interstellar environments should also be common, but surprisingly, astrophysicists detect only low levels of the gaseous kind. This implies to researchers that the missing iron exists in some kind of solid form or molecular state, yet identifying its hiding place has remained elusive.
A team of cosmo-chemists at Arizona State University, with support from the W.M. Keck Foundation and access to XSEDE-allocated resources, now claims that the mystery may be simpler than it seems. The iron isn't really missing, they say. Instead, it's hiding in plain sight. The iron is believed to have combined with carbon molecules to form molecular chains called iron pseudocarbynes. The spectra of these chains are almost identical with the much more common chains of carbon atoms, long known to be abundant in interstellar space.
Iron (Fe) pseudocarbynes are likely widespread in the interstellar medium, where extremely cold temperatures would lead carbon chains to condense on Fe clusters. Over eons, the formation of complex organic molecules would be facilitated from Fe pseudocarbynes. The model shows a hydrogen-capped carbon chain attached to an Fe13 cluster (iron atoms are shown as reddish brown, carbon is gray, hydrogen is light gray).

Program Announcements
Invitation to submit Requests for Interoperable Support Services between PRACE, XSEDE, and RIST by collaborating teams
The PRACE Board of Directors, the XSEDE Senior Management Team and the RIST Kobe Centre are now inviting requests from new or established collaborative teams spanning Europe, the U.S.A, and/or Japan whose research could be accelerated by coordinated access to staff expertise and/or high-end HPC resources from PRACE, XSEDE and RIST. In this initial opportunity, research teams can request staff support services from all three organizations as well as small-scale allocations on resources available via PRACE and XSEDE.
All requests can be submitted via   starting November 25, 2019 but must be submitted no later than December 20, 2019 by 11:59pm. Requests should articulate the anticipated benefits to the collaboration of the joint support efforts from the infrastructure organizations. The selected proposals will receive support from PRACE, XSEDE, and RIST, as appropriate, to improve the scientific productivity of the collaborators.
XSEDE Service Providers jointly receive HPCwire's Top HPC-Enabled Scientific Achievement
Several XSEDE Service Providers received recognition in the 16th annual HPCwire Readers' and Editors' Choice Awards, presented during SC19.
Notably, SDSC, TACC, and PSC were jointly awarded the Top HPC-Enabled Scientific Achievement for simulations conducted via XSEDE which helped reveal groundbreaking insight into gravitational waves, or invisible space ripples, by analyzing neutron star structures and mergers — with Perimeter Institute for Theoretical Physics (Ontario, Canada) and Theoretical Astrophysics Program (University of Arizona).
The full list of awardees may be found here.
Apply by Jan. 27 for the 2020 International HPC Summer School Program
Graduate students and postdoctoral scholars are invited to apply for the eleventh International Summer School on HPC Challenges in Computational Sciences, to be held from July 12 to 17, 2020, at the University of Toronto, Canada.
Applications are due Jan. 27, 2020. The expense-paid program will benefit scholars from around the world who use advanced computing in their research. The ideal candidate does not need to be an expert in HPC! More information and how to apply may be found at the link below.
Students and leading computational scientist mentors at the 2018 IHPCSS in Ostrava, Czech Republic.
New XSEDE Highlights Book now available!
XSEDE is thrilled to release the seventh edition of our XSEDE Highlights Book, featuring 12 different stories of scientific breakthroughs made possible through access to XSEDE-allocated resources, services, and assistance.

Help raise the bar for transfer performance at your institution!
ESnet, Globus and Indiana University are hosting a Data Mobility Exhibition through August 2020. The goal? Improve your ability to predictably and efficiently move scientific data between experimental sources, processing facilities, diverse storage systems, and collaborators. Participants will learn more about where their transfer environment stands today and will have a chance to work with ESnet, Globus and other participants to improve your current state.
Trusted CI now accepting applications for Open Science Cybersecurity Fellows program
Trusted CI's inaugural 2019 cohort of Fellows was an amazing success with six Fellows from research technologies, astrophysics, criminal justice, network and combinatorial optimization, and computer engineering. Trusted CI is now pleased to announce the call for applications for 2020 Trusted CI Fellows. Another cohort of six fellows will receive training from and work closely with Trusted CI to expand their own understanding of trustworthy science and further empower the NSF community to secure its own research.
The deadline for applications is January 17th, 2020. There will be a special Trusted CI webinar on the Fellow application process on December 17th at 10am Eastern time.
