The Image Reduction and Analysis Facility (IRAF) is a general purpose software system for the reduction and analysis of scientific data. The IRAF system provides a good selection of programs for general image processing and graphics applications, plus a large selection of programs for the reduction and analysis of optical astronomy data. The system also provides a complete modern scientific programming environment, making it straightforward for institutions using IRAF to add their own software to the system. Every effort has been made to make the system as portable and device independent as possible, so that the system may be used on a wide variety of host computers and operating systems with a wide variety of graphics and image display devices.read more

TL;DR: The Zwicky Transient Facility (ZTF) as mentioned in this paper is a new optical time-domain survey that uses the Palomar 48 inch Schmidt telescope, which provides a 47 deg^2 field of view and 8 s readout time, yielding more than an order of magnitude improvement in survey speed relative to its predecessor survey.

TL;DR: In this paper, spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular galaxies (dIrrs) were analyzed and it was shown that dIrrs obey the same mass-metallicity relation as the dwarf spheroidal (dSph) satellites of both the Milky Way and M31: Z_* ∝ M_*^(0.30±0.02).

RVSAO 2.0: Digital Redshifts and Radial Velocities
Michael J. Kurtz,Douglas J. Mink +1 more
TL;DR: In this article, the authors developed a new methodology for building spectral templates for galaxy redshifts, using the new templates for the FAST spectrograph as an example, and showed that a two-dimensional spectral classification of galaxy spectra can be developed using their emission- and absorption-line templates as physically orthogonal basis vectors.
