Generalized Rotation Curves of the Milky Way from the GAIA DR3 Data Set: Constraints on Mass Models

The Astrophysical Journal
The circular velocity curve traced by stars provides a direct means of investigating the potential and mass distribution of the Milky Way. Recent measurements of the Galaxy’s rotation curve have revealed a significant decrease in velocity for Galactic ...

Uniform Silicon Isotope Ratios Across the Milky Way Galaxy

, 2017
We report the relative abundances of the three stable isotopes of silicon, $^{28}$Si, $^{29}$Si and $^{30}$Si, across the Galaxy using the $v = 0, J = 1 \to 0$ transition of silicon monoxide. The chosen sources represent a range in Galactocentric radii ($

Investigating halo substructures with annual modulation signature [PDF]

, 2006
Galaxy hierarchical formation theories, numerical simulations, the discovery of the Sagittarius Dwarf Elliptical Galaxy (SagDEG) in 1994 and more recent investigations suggest that the dark halo of the Milky Way can have a rich phenomenology containing ...

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

A comparison of the Andromeda and Milky Way galaxies [PDF]

Symposium - International Astronomical Union, 1985
A comparison of some of the basic properties of M31 and the Milky Way indicates that in almost every respect M31 is larger than the Galaxy. It is more luminous, redder, more massive, and of earlier Hubble type. A detailed comparison of the spiral structure, based on optical tracers, for comparable areas in the outer parts of each galaxy shows ...

Multiple Stellar Populations in the Globular Cluster omega Centauri as Tracers of a Merger Event

, 1999
The discovery of the Sagittarius dwarf galaxy, which is being tidally disrupted by and merging with the Milky Way, supports the view that the halo of the Galaxy has been built up at least partially by the accretion of similar dwarf systems.

Our Milky Way as a Pure-Disk Galaxy -- A Challenge for Galaxy Formation [PDF]

, 2010
Bulges are commonly believed to form in the dynamical violence of galaxy collisions and mergers. Here we model the stellar kinematics of the Bulge Radial Velocity Assay (BRAVA), and find no sign that the Milky Way contains a classical bulge formed by ...

Human γδ T Cell Function Is Impaired Upon Mevalonate Pathway Inhibition

Immunology, Volume 175, Issue 3, Page 300-322, July 2025.
Mevalonate pathway is important for the effector function of gammadelta T cells. Inhibition of the pathway in vivo and in vitro impairs cytokine and cytotoxic molecule production by mainly affecting protein prenylation and disturbing intracellular signalling in Vdelta2 T cells. Created with Biorender.

Biopiracy and beauty brands? patent trends of cosmetics and skin care companies

The Journal of World Intellectual Property, Volume 28, Issue 2, Page 640-664, July 2025.
Abstract Concerns about the fairness and equity of ‘biodiscovery’ research endure despite the creation of legal frameworks designed to regulate access and benefit sharing involving genetic resources and associated traditional knowledge. While some industries that engage in biodiscovery have been the subject of sustained scrutiny, others have received ...

What Is Missing from the Local Stellar Halo?

The Astrophysical Journal
The Milky Way’s stellar halo, which extends to >100 kpc, encodes the evolutionary history of our Galaxy. However, most studies of the halo to date have been limited to within a few kiloparsecs of the Sun.
