H II regions in peculiar galaxies

The Astrophysical Journal, 1975
A survey of 32 galaxies, either classified as peculiar or having peculiar distributions of H ii regions, is presented in order to ascertain the range of the peculiarities and the degree to which they are similar. Ten different types are recognized, several of which are interrelated.

Computers in Our Cosmos: Intersections in Geographies of Care, Abolition Geographies and Worker Movements

Transactions of the Institute of British Geographers, EarlyView.
ABSTRACT AI assistants on spacecrafts. Netflix streamed through inter‐planetary communication networks. Colonies on Mars by 2050. While the glamorous public–private ventures into outer space curate discussions on the technical specificities of these proposed projects, this paper reorients discussions on such developments through critical frameworks of ...

Where Have All the Little Red Dots Gone? Supermassive Black Hole Binary Dynamics and Its Impact on Galaxy Properties

The Astrophysical Journal Letters
Recent James Webb Space Telescope observations have revealed a peculiar class of galaxies at redshifts z  ≳ 6, characterized by extremely high central stellar densities and overmassive central supermassive black holes (SMBHs), “little red dots” (LRDs). A

A Morphological Identification and Study of Radio Galaxies from LoTSS DR2 II. Strange and Odd Morphology Extragalactic Radio Sources ‘STROMERSs’

Galaxies
STRange and Odd Morphology Extragalactic Radio Sources (STROMERSs) is a new category of radio galaxies that shows extremely peculiar anatomy. A purely manual visual search is carried out for the identification of such interesting sources.

Radio observations of peculiar galaxies

, 1975
With the 1000-foot radiotelescope of the Arecibo Ionospheric Observatory we have observed the positions of 69 peculiar galaxies classified by Arp (1966). Several radio sources were detected, but they could be chance coincidences. Radio maps of the radio sources are given.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Ultraviolet excess in peculiar galaxies

, 1970
The two colour diagram for the continuum of the Seyfert galaxies has been calculated with a two component model; a stellar component identical to that of the giant elliptical galaxies and the radiation of a gaseous component excited by thermal collisions.

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

SN 2022oqm: A Bright and Multipeaked Calcium-rich Transient

The Astrophysical Journal
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multipeaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kpc from its host galaxy, the face-on spiral galaxy NGC 5875.
