Optical properties and spatial distribution of MgII absorbers from SDSS image stacking

open access: yes, 2007
We present a statistical analysis of the photometric properties and spatial distribution of more than 2,800 MgII absorbers with 0 ...

Multivalent mRNA-DTP vaccines are immunogenic and provide protection from Bordetella pertussis challenge in mice

open access: yesnpj Vaccines
Acellular multivalent vaccines for pertussis (DTaP and Tdap) prevent symptomatic disease and infant mortality, but immunity to Bordetella pertussis infection wanes significantly over time resulting in cyclic epidemics of pertussis.

Ultraviolet spectra of extreme nearby star-forming regions --- approaching a local reference sample for JWST

open access: yes, 2017
Nearby dwarf galaxies provide a unique laboratory in which to test stellar population models below $Z_\odot/2$. Such tests are particularly important for interpreting the surprising high-ionization UV line emission detected at $z>6$ in recent years.

Quasar feedback and the origin of radio emission in radio-quiet quasars

open access: yes, 2014
We conduct kinematic analysis of the SDSS spectra of 568 obscured luminous quasars, with the emphasis on the kinematic structure of the [OIII]5007 emission line. [OIII] emission tends to show blueshifts and blue excess, which indicates that at least part

On Mitigation of the Uncertainty in Nonlinear Matter Clustering for Cosmic Shear Tomography

open access: yes, 2010
We present a new method that deals with the uncertainty in matter-clustering in cosmic shear power spectrum analysis that arises mainly due to poorly understood nonlinear baryonic processes on small-scales.
