…, JP Hughes, PJ Green, RA Jansen… - The Astronomical …, 1999 - iopscience.iop.org
We present 1210 Johnson/Cousins B, V, R, and I photometric observations of 22 recent
Type Ia supernovae (SNe Ia): SNe 1993ac, 1993ae, 1994M, 1994S, 1994T, 1994Q, 1994ae, …

[O ii] as a star formation rate indicator

LJ Kewley, MJ Geller, RA Jansen - The Astronomical Journal, 2004 - iopscience.iop.org
We investigate the [O II] emission line as a star formation rate (SFR) indicator using
integrated spectra of 97 galaxies from the Nearby Field Galaxies Survey (NFGS). The sample …

Accurate wide-range design equations for the frequency-dependent characteristic of parallel coupled microstrip lines

M Kirschning, RH Jansen - IEEE Transactions on Microwave …, 1984 - ieeexplore.ieee.org
In this paper, closed-form expressions are presented which model the frequency-dependent
even- and odd-mode characteristics of parallel coupled microstrip lines with hitherto …

Accurate model for effective dielectric constant of microstrip with validity up to millimetre-wave frequencies

M Kirschning, RH Jansen - Electronics letters, 1982 - infona.pl
A closed-form expression is presented for the effective dielectric constant of single microstrip
lines which is valid with high accuracy up to mm-wave frequencies. The formula given has …

Aperture effects on star formation rate, metallicity, and reddening

LJ Kewley, RA Jansen, MJ Geller - Publications of the …, 2005 - iopscience.iop.org
We use 101 galaxies selected from the Nearby Field Galaxy Survey to investigate the effect
of aperture size on the star formation rate, metallicity, and reddening determinations for …
