Conceptual design of the MAGNUM near-infrared four-band imager (MAGNIFI) and its science cases

Le résumé fourni par la source

We present the results of conceptual designing of a near-infrared four-band simultaneous imaging instrument—the MAGNUM Near-Infrared Four-band Imager (MAGNIFI)—for installation on the 2-m MAGNUM telescope. The MAGNIFI aims to simultaneously capture the Y (1.032µm), J (1.235µm), H (1.162µm), and Ks (2.159µm) bands. Optical design studies have adopted an F-conversion optical system (F/9.19 to F/6), followed by an Offner relay and three beam splitters to divide light into four channels corresponding to the Y, J, H, and Ks bands, thus realizing simultaneous imaging across 0.9--2.3µm. All channels are planned employ InGaAs detectors manufactured by Hamamatsu Photonics, providing a wide field of view of 3.7 arcmin by 3.0 arcmin. MAGNIFI will enable multi-color, near-infrared imaging contributing to both time-domain and multi-messenger astronomy. In this presentation, we introduce the results of the conceptual design of MAGNIFI and outline the science cases the instrument aims to address.
