, 2016 Quenching, the cessation of star formation, is one of the most significant events in the life cycle of galaxies. We show here the first evidence that the Milky Way experienced a generalised quenching of its star formation at the end of its thick disk ...

A Wave-corrected Assessment of the Local Midplane
The Astrophysical JournalAs the number of known Galactic structures mounts thanks to the Gaia Space Telescope, it is now pertinent to study methods for disentangling structures occupying the same regions of the Milky Way. Indeed, understanding the precise form of each individual

The LMC Microlensing Events: Evidence for a Warped and Flaring Milky Way Disk? [PDF]
, 1997 The simplest interpretation of the microlensing events toward the Large Magellanic Cloud detected by the MACHO and EROS collaborations is that about one-third of the halo of our own Milky Way galaxy exists in the form of objects of around 0.5 M☉.

Journal of Applied Polymer Science, EarlyView.ABSTRACT In this study, the electrospinning method was used to create green synthesis sustainable pullulan and whey protein nanofibers loaded with black cumin waste extract. FE‐SEM imaging, FTIR, XRD, DSC, total phenolic content determination, total antioxidant activity determination, and antibacterial activity assessment were used to characterize the ...

Theoretical Models of the Galactic Bulge
, 2015 Near infrared images from the COBE satellite presented the first clear evidence that our Milky Way galaxy contains a boxy shaped bulge. Recent years have witnessed a gradual paradigm shift in the formation and evolution of the Galactic bulge. Bulges were

The Astrophysical JournalWe present an analysis of the structure, kinematics, and chemo-dynamical properties of the Milky Way bulge using RR Lyrae stars from Optical Gravitational Lensing Experiment (OGLE), and giant stars from APOGEE and Gaia that have distances placing them in

On the Formation of Planets in the Milky Way’s Thick Disk
The Astrophysical JournalAbstract Exoplanet demographic surveys have revealed that close-in (≲1 au) small planets orbiting stars in the Milky Way’s thick disk are ∼50% less abundant than those orbiting stars in the Galactic thin disk. One key difference between the two stellar populations is the time at which they emerged: thick-disk stars are the likely product

Observational Constraints of Radial Migration in the Galactic Disk Driven by the Slowing Bar
The Astrophysical Journal LettersRadial migration is an important dynamical effect that has reshaped the Galactic disk, but its origin has yet to be elucidated. In this work, we present evidence that resonant dragging by the corotation of a decelerating bar could be the main driver of ...

LZTS2 Negatively Regulates Centrosomal CEP135 Levels and Microtubule Nucleation
Cytoskeleton, EarlyView.ABSTRACT The microtubule cytoskeleton is a fundamental functional component of the cell. In vertebrate proliferating cells, centrosomes are the primary microtubule organizing center (MTOC), and their dysregulation has been linked to genomic instability and cancer.

, 2013 We present a high resolution simulation of an idealized model to explain the origin of the two young, counter-rotating, sub-parsec scale stellar disks around the supermassive black hole SgrA* at the Center of the Milky Way. In our model, the collision of
