Metallicity gradients through disk Instability: A simple model for the Milky Way's boxy bulge

, 2013
Observations show a clear vertical metallicity gradient in the Galactic bulge, which is often taken as a signature of dissipative processes in the formation of a classical bulge. Various evidence shows, however, that the Milky Way is a barred galaxy with

All‐PEG‐Like Block Copolymers Self‐Assemble into Stealth Nanocarriers for Drug Delivery

Advanced Science, EarlyView.
Self‐assembling nanoparticles composed entirely of POEGMA are engineered by exploiting side‐chain–dependent amphiphilicity and tunable thermoresponsive behavior. These single‐material nanocarriers encapsulate diverse hydrophobic drugs with high efficiency, retain therapeutic activity, improve in vivo efficacy, and evade anti‐PEG antibodies.

An XMM-Newton long look at the accretion disk plasma in the dipping neutron star LMXB 4U 1624–490

Astronomy & Astrophysics
Context. Dipping neutron star low-mass X-ray binaries (NS LMXBs) are systems that exhibit periodic drops in their X-ray light curves. These are thought to be caused by material at the impact point of the gas stream onto the accretion disk, the bulge ...

R Coronae Borealis stars in the Galactic Bulge discovered by EROS-2

, 2008
Rare types of variable star may give unique insight into short-lived stages of stellar evolution. The systematic monitoring of millions of stars and advanced light curve analysis techniques of microlensing surveys make them ideal for discovering also ...

Manipulation of Emergent Collective Excitations via Composition Control in Mixed MPX3 Correlated 2D Antiferromagnets

Advanced Science, EarlyView.
Transition metal and chalcogen substituents are introduced into 2D antiferromagnet, NiPS3, and comprehensive photoluminescence and Raman spectroscopy studies are conducted to investigate how spin orbit entangled exciton and two magnon scattering evolve as functions of substituent concentration.

Modeling Asteroseismic Yields for the Roman Galactic Bulge Time-domain Survey

The Astrophysical Journal
The Galactic Bulge Time-Domain Survey (GBTDS) of the Roman Space Telescope will take high-cadence data of the Galactic bulge. We investigate the asteroseismic potential of this survey for red giants.

Elemental abundance ratios for the bulge of M31

Astronomy & Astrophysics
We present radial trends of metallicity ([Fe/H]) and abundance ratios ([X/Fe]) for several chemical elements–including C, N, Na, and the so-called α-elements (O, Mg, Si, Ca, and Ti)–in the bulge of M31, out to a projected galactocentric distance of ∼0.6 ...
