First planet found by NGTS - it's a monster!

New research, led by Dan Bayliss and Peter Wheatley, has identified an unusual planet NGTS-1b - the largest planet compared to the size of its companion star ever discovered in the universe.

Dan Bayliss, lead author of the research, commented: "The discovery of NGTS-1b was a complete surprise to us - such massive planets were not thought to exist around such small stars. This is the first exoplanet we have found with our new NGTS facility and we are already challenging the received wisdom of how planets form."

Peter Wheatley added, “Having worked for almost a decade to develop NGTS, it is thrilling to see it picking out new and unexpected types of planets."

Mid-infrared light emission > 3 um wavelength from tensile strained GeSn microdisks

Direct bandgap photoluminescence in the 3–5 um wavelength window is demonstrated from GeSn microdisks, suggesting that GeSn alloys are well suited for mid-infrared integrated gas sensors on Si chips.

ATLAS hunting second Higgs boson

After the discovery of the Higgs boson in 2012 a key question is whether it is the only one. The minimal supersymmetric standard model (MSSM) includes five physical Higgs bosons, three of them neutral. ATLAS has just published a search for a second neutral one decaying to tau pairs, covering a wide mass range above that of the discovered one using data collected in the years 2015 and 2016. This is the most sensitve search for such an MSSM Higgs yet.
