The Pristine survey -- XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry

Nicolas F. Martin, Else Starkenburg, Zhen Yuan +38

We used the spectro-photometric information of ~219 million stars from Gaia's DR3 to calculate synthetic, narrow-band, metallicity-sensitive CaHK magnitudes that mimic the observat…

The stability of some galaxy disks is still perplexing

J A Sellwood, R G Carlberg

The problem of how some disk galaxies avoid forming bars remains unsolved. Many galaxy models having reasonable properties continue to manifest vigorous instabilities that rapidly…

Sub-Halo Spreading of Thin Tidal Star Streams

Raymond G. Carlberg, Hayley Agler

Dark matter sub-halos that pass near or through a thin tidal star stream locally increase its velocity dispersion. Subsequent orbital evolution further increases the velocity dispe…

Spiral instabilities: Mode saturation and decay

J A Sellwood, R G Carlberg

This paper continues a series reporting different aspects of the behaviour of disc galaxy simulations that support spiral instabilities. The focus in this paper is to demonstrate h…

The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission

Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40

SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
