Emission Line Astronomy - Coronagraphic Tunable Narrow Band Imaging and Integral Field Spectroscopy. Project
We propose to continue our program of emission line astronomy featuring three areas of emphasis: 1) The distribution and nature of high redshift emission line galaxies, using the Lyman alpha and other rest-frame UV lines; and the study of planetary systems in formation in the first 10 Myrs, with the interplay of circumstellar disks and jets; and spectral differencing of transiting planets. 2) We are extending the capability of our Goddard Fabry-Perot Imager by incorporating a Coronagraphic Integral Field Spectrograph (CIFS), and will continue our observations with the improved instrument. We request support for completing the commissioning of the instrument, and for its maintenance and operation. The CIFS, which has been delivered to the Apache Point Observatory's 3.5-m telescope, consists of a custom microlens array and magnifier section, a grating wheel assembly, and a photon-counting electron-multiplying CCD (EMCCD), within the optical train of the Fabry-Perot. The instrument is switchable between Fabry-Perot and IFS modes. It provides observational support to interpret data from the HST, Spitzer, Chandra, Herschel and soon JWST space observatories with capabilities not available on them, and will be used to develop technology for future NASA flight programs such as WFIRST, and NWO, THEIA, ATLAST and other planet-finding missions. In this period we propose to extend the wavelength coverage of the CIFS, by extending the format of the EMCCD.

Wackerling Catalog of Early-Type Emission-Line Stars
The Wackerling Catalog contains entries for 5326 early-type emission-line stars. Of these stars, 1424 have no spectral classification but are assumed to be of early type. Some 71 percent of the stars in this catalog can also be found in the Mount Wilson and the Mount Wilson-Michigan survey catalogs. The Wackerling Catalog contains numerous cross identifications to other designations (common name, HD, DM, LS, MWC, TON, HIL, WRA, HEN, etc.), rough spectroscopic types, magnitudes (visual and blue), and positions. The version of the Wackerling Catalog on which the HEASARC database is based was obtained from the ADC and differs in some respects from the original published version, notice. This online catalog was originally ingested by the HEASARC in July 1999, based on a machine-readable table obtained from the ADC/CDS data centers. It was updated in May 2020 to reflect updates to the spect_type_code values made by the CDS for improved database compatibility. This is a service provided by NASA HEASARC .
