Processed and unprocessed ices in circumstellar disks
K. Pontoppidan, E. Dartois, W. -F. Thi +1
We present 3-5 micron VLT-ISAAC spectroscopy searching for evidence of methanol ices in edge-on disks of young embedded stars. Examples include the disks of L1489 IRS in Taurus and…

Results from a VLT-ISAAC survey of ices and gas around young stellar objects
K. M. Pontoppidan, H. Fraser, F. L. Schoeier +3
General results from a 3-5 micron spectroscopic survey of nearby low-mass young stellar objects are presented. L and M-band spectra have been obtained of \~50 low mass embedded you…

Distortion of the SED of High-z Luminous Infrared Galaxies by Strong Lensing
K. M. Pontoppidan, T. Wiklind
We present a model to estimate the effect of differential magnification on the SED of high-z ULIRGs. It is found that the ratio of the high temperature component to the low tempera…
