Visual and Near-infrared Astronomy
Multimessenger Astronomy in Practice, 2021The first non-electromagnetic messengers from space were discovered in the early 20th century, but it is only now that multimessenger astronomy is coming into its own. The aim of Multimessenger Astronomy in Practice is to aid an astronomer who is new to research in a particular area of multimessenger astronomy.

LINC-NIRVANA (LN) is the near-infrared, Fizeau-type imaging interferometer for the large binocular telescope (LBT) on Mt. Graham, Arizona (elevation of 3267 m). The instrument is currently being built by a consortium of German and Italian institutes under the leadership of the Max Planck Institute for Astronomy in Heidelberg, Germany.

A NICMOS-3 based spectrograph for near infrared astronomy
Experimental Astronomy, 1994We describe a design for a compact cooled spectrograph which incorporates two cameras and two collimators to achieve high throughput from 0.8 to 2.5μm. The spectrograph utilizes multiple NICMOS 3 arrays, specially mounted to minimize their separation in the spectral dimension.

Limitations of ground based near and far infrared astronomy
Infrared Physics, 1975Abstract The possibilities of ground based infrared astronomy are discussed. It is shown that telescopes used up to now are not optimized and that the Diffraction Limited Detectivity conditions (DLD) cannot be reached, in the near infrared, by the larger telescopes. The maximum useful diameters for near i.r. and far i.r.

Infrared Spectroscopy of Micro-Organisms near 3.4 μm in Relation to Geology and Astronomy
Astrophysics and Space Science, 1982Microorganisms sealed in KBr discs have an absorption spectrum over the 2.5-15 μm waveband that shows thermal stability as they are heated in an inert atmosphere to temperatures of about 400 °C. Microfossils tightly sealed within cavities in rocks could be endowed with similar properties of thermal stability.

A discussion on infared astronomy - Near infrared night sky background
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969Abstract We have carried out near infrared observations on wide fields of the sky, using both a rocket-borne telescope and ground-based equipment. The rocket observations covered the spectral range of 1 to 8 μm. The ground-based observations were carried out in a narrow spectral region around 1.085 μm.

SPIREX-near infrared astronomy from the South Pole
Experimental Astronomy, 1994Over the next several years we will deploy a series of spectrometers, imagers, and telescopes at the South Pole as part of a project named SPIREX — for South Pole Infrared Explorer. Our goal is to survey a substantial area of the sky to study the origins of galaxies and stars.
