Machine learning and related methods will be crucial for automatically classifying transients as they happen in order to best allocate follow-up resources. Such techniques cannot be used off the shelf, but must be developed by the community as a whole.

Reviews 07 August Observational properties of thermonuclear supernovae Thermonuclear supernovae — those involving the explosion of a white dwarf — and particularly type-Ia supernovae, have become indispensable tools for observationally measuring the expansion of the Universe. Nature Astronomy 3 , Nature Astronomy , Research 08 July Realistic simulations of galaxy formation in f R modified gravity Full cosmological hydrodynamical simulations employing modified gravity find that disk galaxies can form and their stellar properties are only mildly affected.
Research 24 June Observational evidence for bar formation in disk galaxies via cluster—cluster interaction A study of nearby galaxy clusters from the Sloan survey shows that barred galaxies appear more frequently in interacting clusters, indicating that cluster—cluster interaction can play an important part in bar formation.

News 16 July How fast is the Universe expanding?
Cosmologists just got more confused Hotly anticipated technique fails to resolve disagreement over speed of cosmic expansion — for now. Nature Research menu. Search Article search Search. While the Planck mission has been completed, members of MPA are actively analysing the data to study the physics of the early universe using the CMB and the late-time universe using galaxy clusters. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion.
Currently the fourth incarnation of the survey includes the Baryon Acoustic Oscillation Spectroscopic Survey BOSS , which aims to provide measurements of the geometry and late-time expansion of the Universe with unprecedented precision.
Cosmology Is in Crisis Over How to Measure the Universe
The expected starting date of the survey is in Eiichiro Komatsu is a member of the HETDEX collaboration and is leading the cosmological interpretation of the data for late-time cosmic acceleration, inflation, and mass of neutrinos. The instrument consists of three parts: blue, red, and infrared arms, covering a wide wavelength range of nm with the resolution of 0.
