"The results of morphological and spectral study of the galaxies Kaz 5,
Kaz 92, and Kaz 390 are presented. The observations were made on the
2.6-m telescope at the Byurakan Observatory with the VAGR microlenses
spectrograph," scientists writing in the journal Astrophysics report
(see also Astrophysics).
"Isophotes of the images of the galaxies are constructed in the H
alpha, [NII] lambda lambda 6584 , 6548, and [SII] lambda lambda 6731,
6717 emission lines and in the continuum. The masses of Kaz 5 and Kaz
92 are determined to be 8.6 x 10(8) M-aS (TM) and 6.1 x 10(9) M-aS
(TM) , respectively. The mass of the gaseous component in the centers
of regions I and IV of Kaz 390, which encompass a 1 pixel area, are
also determined. The morphological structure of the central region
of Kaz 5 in the observed spectral range, lambda lambda 6400-6800A…,
differs completely from the structure of the same part of the galaxy
observed with the 6-m and 2.5-m telescopes. It is shown that these
differences in the structure in images of Kaz 5 are mostly explained
by the comparatively low resolution of the telescope in combination
with the VAGR spectrograph. Absorbing matter also contributes to this
effect," wrote V.Z. Adibekyan and colleagues.
The researchers concluded: "It is also shown that a "deficit" of
nitrogen has been observed in the region of Kaz 390 studied here
(a circle of diameter 40aEuro(3))."
Adibekyan and colleagues published their study in Astrophysics (The
morphological and spectral investigation of the galaxies Kaz 5,
Kaz 92, and Kaz 390. Astrophysics, 2009;52(1):54-65).
