Developments in Housing Law and Reasonable Accommodations for New York City Residents with Disabilities

This Essay examines the New York Human Rights Law, which prohibits discrimination in the sale or rental of a housing accommodation and provides persons with disabilities the right to request and receive reasonable accommodations from their housing providers. The Essay concludes that the recent interpretation of this law by New York City Commission on Human Rights Law is a move toward protecting the rights of persons with disabilities and removing unnecessary discrimination from their lives

MALT90 molecular content on high-mass IR-dark clumps

High mass stars form in groups or clusters within massive cores in dense molecular clumps with sizes of 1pc and masses of 200Msun which are important laboratories for high-mass star formation in order to study the initial conditions. We investigate the physical and chemical properties of high-mass clumps in order to better understand the early evolutionary stages and find targets that show star formation signs. We selected the high-mass clumps from ATLASGAL survey that were identified as dark at 8/24$\mu$m wavelengths and used MALT90 data which provides a molecular line set to investigate the physical and chemical conditions in early evolutionary stages. Eleven sources have significant SiO detection (over 3$\sigma$) which usually indicates outflow activities. Thirteen sources are found with blue profiles in both or either HCO$^+$ and/or HNC lines and clump mass infall rates are estimated to be in the range of 0.2E+3 Msunyr$^{-1}$ $-$ 1.8E-2 Msunyr$^{-1}$. The excitation temperature is obtained as <24K for all sources. The column densities for optically thin lines of H$^{13}$CO$^{+}$ and HN$^{13}$C are in the range of 0.4-8.8(E+12) cm$^{-2}$, and 0.9-11.9(E+12) cm$^{-2}$, respectively, while it is in the range of 0.1-7.5(E+14) cm$^{-2}$ for HCO$^{+}$ and HNC lines. The column densities for N$_{2}$H$^{+}$ were ranging between 4.4-275.7(E+12) cm$^{-2}$ as expected from cold dense regions. Large line widths of N$_{2}$H$^{+}$ might indicate turbulence and large line widths of HCO$^{+}$, HNC, and SiO indicate outflow activities. Mean optical depths are 20.32, and 23.19 for optically thick HCO$^{+}$ and HCN lines, and 0.39 and 0.45 for their optically thin isotopologues H$^{13}$CO$^{+}$ and HN$^{13}$C, respectively. This study reveals the physical and chemical properties of 30 high-mass IR-dark clumps and the interesting targets among them based on their emission line morphology and kinematics.Comment: 59 pages, 11 figures, Accepted for publication in A &

Flares observed with XMM-Newton and the VLA

We present lightcurves obtained in X-ray by the XMM-Newton EPIC cameras and simultaneous radio lightcurves obtained with the VLA for five active M-type flare stars. A number of flare events were observed, and by comparing radio with X-ray data, we consider various possible flare mechanisms. In cases where there seems to be a clear correlation between radio and X-ray activity, we use an energy budget argument to show that the heating which leads to the X-ray emission could be due to the same particles emitting in the radio. In cases where there is radio activity without corresponding X-ray activity, we argue that the radio emission is likely to arise from coherent processes involving comparatively few particles. In one case, we are able to show from polarization of the radio emission that this is almost certainly the case. Cases for which X-ray activity is seen without corresponding radio activity are more difficult to explain. We suggest that the heating particles may be accelerated to very high energy, and the resulting synchrotron radio emission may be beamed in directions other than the line of sight.Comment: 12 pages, 10 figure
