2025年2月18日 · A detailed photometric analysis of NGC 3259 using HST images provides a central spheroid stellar mass estimate 25 times lower than expected from the MBH −M∗sph relation, making this galaxy a strong outlier.

NGC 3259 is a barred spiral galaxy located approximately 90 [2] million light-years from Earth, in the Ursa Major constellation. It has the morphological classification SAB (rs)bc, [3] which indicates that it is a spiral galaxy with a weak bar across the nucleus (SAB), an incomplete inner ring structure circling the bar (rs), and moderate to ...

Low-mass active galactic nuclei (AGNs) can provide important constraints on the formation and evolution of supermassive black holes (SMBHs), a central challenge in modern cosmology.

2012年1月9日 · NGC 3259 is a bright barred spiral galaxy located approximately 110 million light-years from Earth. Being a fully-formed active galaxy, its bright central bulge hosts a supermassive black hole, whose huge appetite for matter explains the high luminosity of the galaxy’s core: as it devours its surroundings, the black hole emits intense ...

2022年4月8日 · Physical Information: Based on a recessional velocity of 1685 km/sec (and H0 = 70 km/sec/Mpc), NGC 3259 is about 75 to 80 million light years away, in good agreement with widely varying redshift-independent distance estimates of about 55 to 135 million light years.

2025年2月18日 · Our present study of NGC 3259 at D=27 Mpc with the Binospec integral field unit spectrograph complemented with Keck Echelle Spectrograph and Imager observations demonstrates the need for and the...

2012年8月23日 · About 110 million light years away, the bright, barred spiral galaxy NGC 3259 was just forming stars in dark bands of dust and gas. Here on the part of the Earth where NASA's Goddard Space Flight Center would eventually be built, a plant-eating dinosaur sensed predators nearby and quickened its pace, leaving a deep imprint in the Cretaceous mud.

NGC 3259 是位于 大熊座 的一个 星系。 它的 赤经 为 1032.6， 赤纬 为 65° 3′，大小 2.3′。

NGC 3259 is a bright barred spiral galaxy located approximately 110 million light-years from Earth. Being a fully-formed active galaxy, its bright central bulge hosts a supermassive black hole, whose huge appetite for matter explains the high luminosity of the galaxys core: as it devours its surroundings, the black hole emits intense radiation ...
