With the discovery of GW170817 in gravitational waves, and the discovery of an associated short gamma-ray burst, and the discovery of an associated optical afterglow, we have finally entered the era of gravitational-wave multi-messenger astronomy. I will discuss LIGO/Vigo's detection of this binary coalescence, and explore some of the scientific implications, including confirmation of the kilonova model and implications for the origin of gold and platinum in the universe, tests of general relativity, and the first standard siren measurement of the Hubble constant. GW170817 represents a momentous development in gravitational-wave astronomy, and the birth of gravitational-wave cosmology.

CMB-S4 Collaboration Workshop
March 5 - 7, 2018 | Argonne National Laboratory
Website

The CMB-S4 Collaboration Workshop at Argonne National Laboratory will continue the series of workshops for the CMB community, meant to define the 'Stage-4' ground-based cosmic microwave background (CMB) experiment. The meeting will be held on the Argonne site March 5-7th, 2018, with full-day meetings March 5th and 6th, and splinter meetings the morning of March 7th. This meeting comes at an exciting time for the CMB-S4 community. Following the August 2017 Harvard workshop and 6 months of working group meetings, we will work to establish the formal CMB-S4 Collaboration. Following the acceptance of the report of the CMB-S4 Concept Definition task force, we will work toward the conceptual design and preparations for the Decadal Survey, as well as continuing explorations of next-generation hardware technologies.

The meeting is open to all members of the CMB community and thanks to the support received from Argonne National Laboratory and KICP, there is no registration fee.
