Probing the History of the Galaxy Assembly of the Counterrotating Disk Galaxy PGC 66551

The Astrophysical Journal
Stellar counterrotation in disk galaxies directly relates to the complex phenomenon of the disk mass assembly believed to be driven by external processes, such as accretion and mergers.

Physical correlations of the scatter between galaxy mass, stellar content, and halo mass

, 2020
We use the UniverseMachine to analyse the source of scatter between the central galaxy mass, the total stellar mass in the halo, and the dark matter halo mass, for massive (M-vir > 10(13) M-circle dot) haloes.

Attitudes and behaviours of consumers towards plant‐based yoghurt alternatives: a cross‐cultural study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Increased awareness of sustainable food production and vegan, vegetarian and flexitarian diets are driving the growth in dairy substitutes, particularly plant‐based yoghurts. To understand consumer perception or mind‐set and facilitate adoption of plant‐based yoghurt products, a multi‐phase study using both qualitative and ...

Blue Supergiants in the Pinwheel Galaxy M101: Comparison with H II Region Chemical Abundances, Spectroscopic Distance, and an Independent Determination of the Hubble Constant

The Astrophysical Journal
We present a quantitative spectroscopic study of 13 blue supergiant stars in the Pinwheel Galaxy M101, based on data obtained with the Low Resolution Imaging Spectrometer available at the Keck I telescope.

The multiple corrugations in the Galactic disk derived from the LAMOST and Gaia survey data

Astronomy & Astrophysics
Context. Large spectroscopic and astrometric surveys have revealed complex wave-like features in the Milky Way disk, suggesting that its kinematic and chemical structures are shaped by time-dependent perturbations.

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Star Formation and Dust in the Cosmic Web

The Astrophysical Journal
The large-scale environment of the cosmic web is believed to impact galaxy evolution, but there is still no consensus regarding the mechanisms. We use a semi-analytic model (SAM) galaxy catalog to study the star formation and dust content of local ...

Two phase galaxy formation: the gas content of normal galaxies [PDF]

, 2010
We investigate the atomic (HI) and molecular (H2) Hydrogen content of normal galaxies by combining observational studies linking galaxy stellar and gas budgets to their host dark matter (DM) properties, with a physically grounded galaxy formation model ...
