“…As a supplement to the extended one-dimensional kinematic cuts obtained with a long slit, we had calculated two-dimensional line-of-sight velocity maps of the gas and stars for the galactic center from the IFU datacube obtained with the SAURON integral-field spectrograph (Bacon et al 2001). The galaxy NGC 4143 was observed as a part of the ATLAS-3D project the MaNGaL data is similar to that of ordinary direct images with narrow filters and is described in Moiseev et al(2020). After the continuum subtraction, we obtained maps of the total galaxy field in the Hα and [NII]λ6583 emission lines.…”

We present our results of the spectroscopic study of the lenticular galaxy NGC 4143 -an outskirt member of the Ursa Major cluster. Using the observations at the 6-m SAO RAS telescope with the SCORPIO-2 spectrograph and also the archive data of panoramic spectroscopy with the SAURON IFU at the WHT, we have detected an extended inclined gaseous disk which is traced up to a distance of about 3.5 kpc from the center, with a spin approximately opposite to the spin of the stellar disk.The galaxy images in the H-alpha and [NII]λ6583 emission lines obtained at the 2.5-m CMO SAI MSU telescope with the MaNGaL instrument have shown that the emission lines are excited by a shock wave. A spiral structure that is absent in the stellar disk of the galaxy is clearly seen in the brightness distribution of ionized-gas lines (H-alpha and [NII] from the MaNGaL data and [OIII] from the SAURON data). A complex analysis of both the Lick index distribution along the radius and of the integrated colors, including the ultraviolet measurements with the GALEX space telescope and the near-infrared measurements with the WISE space telescope, has shown that there has been no star formation in the galaxy, perhaps, for the last 10 Gyr. Thus, the recent external-gas accretion detected in NGC 4143 from its kinematics, was not accompanied by star formation, probably, due to an inclined direction of the gas inflow onto the disk.

“…The lowest-order interferometer (IFP20) is used for observations in the tunable filter mode when only a small part of ∆λ is scanned, and therefore the parameter n z is unimportant in that case. More details about this type of observations can be found in Moiseev et al (2020). Fig.…”

“…The latter gives ∆λ = 200-600 Å for the Hα line. Isolating such a wide band is not a problem for modern intermediate-band interference filters and is practically realized in the case of the FPI operating in the tunable filter mode (Veilleux et al, 2010;Moiseev et al, 2020). Systems based on dual FPIs have long been efficiently operated on solar telescopes (see, for example Kentischer et al, 1998) and have even been used to observe bright comets (Morgenthaler et al, 2001).…”

The scanning Fabry-Perot interferometer (FPI) -is the oldest method of optical 3D spectroscopy. It is still in use because of the high spectral resolution it provides over a large field of view. The history of the application of this method for the study of extended ob jects (nebulae and galaxies) and the technique of data reduction and analysis are discussed. The paper focuses on the performing observations with the scanning FPI on the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS). The instrument is currently used as a part of the SCORPIO-2 multimode focal reducer. The results of studies of various galactic and extragalactic objects with the scanning FPI on the 6-m telescope-star-forming regions and young stellar objects, spiral, ring, dwarf and interacting galaxies, ionization cones of active galactic nuclei, galactic winds, etc. are briefly discussed. Further prospects for research with the scanning FPI of the SAO RAS are discussed.

“…ADAM (Afanasiev, Dodonov, Amirkhanyan, & Moiseev, 2016) is low-and medium-resolution spectrograph for 1.6-m Russian AZT-33IK telescope. The Mapper of Narrow Galaxy Lines, or MaNGaL 2 (Moiseev, Perepelitsyn, & Oparin, 2020) was developed and manufactured for the 1-m telescope of SAO and the 2.5-m telescope of the Sternberg Astronomical Institute of the Moscow State University. All these instruments were created for specific tasks and now are efficiently working.…”

Universal focal reducer for small telescopes

et al. 2021

This paper is devoted to the memory of Dr. Victor Afanasiev and his immense legacy. The report highlights the capabilities of two new instruments tested at the 1-meter Zeiss-1000 telescope of SAO RAS: the Stokes Polarimeter (StoP) and the MAGIC focal reducer. Optimized for the study of active galactic nuclei (AGN), methodically, these instruments are suitable for a wide range of small telescope tasks. The fields of view of StoP and MAGIC are 6' and 13' for direct images, respectively. The StoP device allows one to conduct photometric observations and polarimetric ones with a double Wollaston prism; the spectral mode was added to MAGIC. For a starlike target up to 14 mag in medium-band filters with a seeing of 1' ' for 20 minutes of total exposure, the photometry accuracy is better than 0.01 mag and the polarization accuracy is better than 0.6%. The available spectral range obtained with the volume phase holographic grating in MAGIC is 4000-7200AA with a dispersion of 2A/px. StoP and MAGIC received the first light in 2020 and are used in test mode at the Zeiss-1000. The report discusses the first results obtained by the authors with new instruments, as well as further prospects.
