Novel Instruments for Transient Spectroscopy

The field of time-domain astronomy is going through a golden age. The number of on-going optical surveys, such as ZTF, PanSTARRS, CSS, and SkyMapper, as well as the Large Synoptic Survey Telescope (LSST, to be commissioned in the near future), will keep this field vibrant well into the next decade. Moreover, the detection of an EM counterpart to a gravitational waves source detected by LIGO have further increased interest in the transient sky. While detection of transients such as SNe and Tidal Disruption Events (TDEs) is mainly done with imaging surveys, detailed studies of the underlying physics driving these phenomena requires additional information in the form of observed spectra. In the following seminar I will present two instruments designed for detailed transient spectroscopy: the first being the Binospec IFU unit for the Binospec spectrograph mounted on the MMT, while the second is the SOXS spectrograph for ESO New Technology Telescope. These instruments take advantage of advanced dispersive elements, making them ideal for spectroscopy of faint objects across the visible and NIR wavebands.
