“…A ∼100 kpc long tidal arm is detected in the spiral galaxy M 83 (Koribalski et al 2018), likely formed by accretion of a dwarf irregular galaxy. Two of the longest H i tidal tails known so far (length 160 and 250 kpc) are both associated with galaxy groups in the outskirts of Abell 1367 (Scott et al 2012).…”

“…While this list includes many prominent H i features, some of which are also mentioned here, it is dominated by gas-rich galaxy pairs and mergers (e.g., NGC 6872/IC 4970 studied by Horellou & Koribalski 2007). Detached H i clouds/streams, 2 Bärbel S. Koribalski often without stellar counterparts, are typically found in wide-field H i surveys (e.g., Ryder et al 2001, Scott et al 2012 carried out with single dish telescopes. We are now commencing an era of wide-field interferometric H i surveys with recent results from ASKAP and MeerKat, including the discovery of tidal tails, presented by Lee-Waddell et al (2019) and Serra et al (2019), respectively.…”

Here I present a brief review of interacting galaxy systems with extended low surface brightness (LSB) hydrogen tails and similar structures. Typically found in merging pairs, galaxy groups and clusters, H i features in galaxy surroundings can span many hundreds of kpc, tracing gravitational interactions between galaxies and ram pressure forces moving through the intragroup/cluster medium. Upcoming large H i surveys, e.g., with the wide-field (FOV = 30 square degrees) Phased Array Feeds on the Australian SKA Pathfinder (ASKAP), will provide a census of LSB structures in the Local Universe. By recording and comparing the properties (length, shape, H i mass, etc.) of these observed structures and their associated galaxies, we can -using numerical simulations -try to establish their origin and evolutionary path.

From Eugenicists to Family Planners: America’s Religious Promoters of Contraception

Early proponents of contraception among American religious groups were staunch eugenicists who promoted birth control in the hopes of curtailing the "runaway fertility" of poor Catholic and Jewish immigrants. By the early 1930s, their campaign to legalize contraception was largely successful, but eugenics would soon go from being a sign of progressive politics and enlightened scientific understanding to a dirty word associated with Hitler. By examining the statements of all of the early liberalizers on contraception from 1920 to 1965, this paper demonstrates that although these groups purged their statements on contraception of the word eugenics by the end of WWII, the fertility of "poor others" remained their focus for the next few decades. Talk of "race suicide" changed to talk of "responsible parenthood" as their focus moved away from the whitening Irish, Italian, and Jewish immigrants to the poor in the Third World and Americans in the inner cities.
