The gray-scale and contours show the spatial distribution of different transitions of HCONH2. The figures are listed in order of increasing upper state energy. The first figure is the map of HCONH2 11,1-00,0 at 82549.562 MHz. The contour levels start at 2 K km s−1 with a step of 0.4 K km s−1 . The second figure is the map of HCONH2 40,4-30,3 at 84542.330 MHz. The contour levels start at 7 K km s−1 with a step of 2.5 K km s−1 . The third figure is the map of HCONH2 41,3-31,2 at 87848.874 MHz. The contour levels start at 8.4 K km s−1 with a step of 3 K km s−1 . The fourth figure is the map of HCONH2 42,2-32,1 at 85093.272 MHz. The contour levels start at 3.3 K km s−1 with a step of 3 K km s−1 . The fiveth figure is the map of HCONH2 42,3-32,2 at 84807.795 MHz. The contour levels start at 3 K km s−1 with a step of 2 K km s−1 . The sixth figure is the map of HCONH2 43,2-33,1 and 43,1-33,0 at 84888.994 MHz and 84890.987, respectively. The contour levels start at 2.5 K km s−1 with a step of 2.5 K km s−1 . Sgr B2(N), Sgr B2(M), and G+0.693 are labeled with ′′ × ”. The beam size are shown in the left corner of each panel. -- astro-ph.GA

Mapping Observations of Peptide-like Molecules Around Sagittarius B2

by Keith CowingOctober 25, 2023October 25, 2023

Peptide-like molecule, which has a close connection with the origin of life, has been detected in universe. Mapping observations of HCONH2 and CH3CONH2, two simplest peptide-like molecules, are performed towards […]

AFGL 2591 integrated intensity R TAdv (K km s−1 ) maps of rotational transition lines spanning a range of energy levels. The upper state energy level is indicated in the top right-hand corner and the beam size in the bottom left-hand corner. The source VLA 3 is noted by a white or black ‘x’. CH3CCH, in the first column, c-C3H2, in the second, H2CO, in the third, have contour levels of 10, 20, 30, and 40 times the noise level of the respective frequency range. CH3OH, in the fourth column, has contour levels of 10, 20, 40, 80, and 120 times the noise level of the respective frequency range. -- astro-ph.SR

Parsec Scales Of Carbon Chain And Complex Organic Molecules In AFGL 2591 And IRAS 20126

by Keith CowingAugust 21, 2023August 21, 2023

(Abridged) There is a diverse chemical inventory in protostellar regions leading to the classification of extreme types of systems. Warm carbon chain chemistry sources, for one, are the warm and […]
