The properties of a large sample of low surface brightness galaxies from SDSS (2009)

Liang, Y. C., Zhong, G. H., Chen, X. Y., Gao, D., Hammer, F., Liu, F. S., ...

A large sample of low surface brightness (LSB) disk galaxies is selected from SDSS with B-band central surface brightness mu_0(B) from 22 to 24.5 mag arcsec^(-2). Some of their properties are...

Stellar population analysis on local infrared-selected galaxies (2008)

Chen, X. Y., Liang, Y. C., Hammer, F., Zhao, Y. H., Zhong, G. H.

To study the stellar population of local infrared galaxies, which contain star-forming galaxies, composite galaxies, LINERs, and Seyfert 2s. We also want to find whether infrared luminosity and...

IMAGES. I. Strong evolution of galaxy kinematics since z = 1 (2008)

Yang, Y., Flores, H., Hammer, F., Neichel, B., Puech, M., Nesvadba, N., ...

Nearly half the stellar mass of present-day spiral galaxies has formed since z = 1, and galaxy kinematics is an ideal tool to identify the underlying mechanisms responsible for the galaxy mass...

IMAGES IV: strong evolution of the oxygen abundance in gaseous phases of intermediate mass galaxies from z ~ 0.8 (2008)

Rodrigues, M., Hammer, F., Flores, H., Puech, M., Liang, Y. C., Fuentes-Carrera, I., ...

Context: Intermediate mass galaxies (> 1010 M_o) at z ~ 0.6 are the likeliest progenitors of the present-day, numerous population of spirals. There is growing evidence that they have evolved rapidly...

IMAGES. III. The evolution of the near-infrared Tully-Fisher relation over the last 6 Gyr (2008)

Puech, M., Flores, H., Hammer, F., Yang, Y., Neichel, B., Lehnert, M., ...

Using the multi-integral field spectrograph GIRAFFE at VLT, we have derived the K-band Tully-Fisher relation (TFR) at z ˜ 0.6 for a representative sample of 65 galaxies with emission lines...

IMAGES. II. A surprisingly low fraction of undisturbed rotating spiral disks at z ~ 0.6 The morpho-kinematical relation 6 Gyr ago (2008)

Neichel, B., Hammer, F., Puech, M., Flores, H., Lehnert, M., Rawat, A., ...

We present a first combined analysis of the morphological and dynamical properties for the intermediate-mass Galaxy Evolution Sequence (IMAGES) sample. It is a representative sample of 52...

SDSS J121811.0+465501.2: a new Low Surface Brightness Galaxy with low metallicity (2007)

Liang, Y. C., Hu, J. Y., Liu, F. S., Liu, Z. T.

We serendipitously find a new nearby Low Surface Brightness (LSB) galaxy from SDSS database. We estimate oxygen abundance of its H II region SDSS J121811.0+465501.2 from electron temperature, as well...

Better Bell-inequality violation by collective measurements (2006)

Liang, Y. C., Doherty, A. C.

The standard Bell-inequality experiments test for violation of local realism by repeatedly making local measurements on individual copies of an entangled quantum state. Here we investigate the...
