WebThe galaxy, known as NGC 7331 and sometimes referred to as our galaxy's twin, is found in the constellation Pegasus at a distance of 50 million light-years. This inclined galaxy was discovered in 1784 by William Herschel, who also discovered infrared light. WebWe use new deep 21 cm H I observations of the moderately inclined galaxy NGC 4559 in the HALOGAS survey to investigate the properties of extraplanar gas. We use TiRiFiC to construct simulated data cubes to match the H I observations. We find that a thick-disk component of scale height ∼2 kpc, characterized by a negative vertical gradient in its …

We identified a warp simply as a large-scale systematic devi-ation of galaxy isophotes from the plane defined by the inner (≤1/2 of optical radius) region of a galaxy.
