  author={Souradip Bhattacharyya and Sanskriti Das and Anjali Gupta and Smita Mathur and Yair Krongold},
We present XMM-Newton observations around the sightline of Mrk 421. The emission spectrum of the Milky Way circumgalactic medium (CGM) shows that a two phase model is a better fit to the data compared to a single phase model; in addition to the warm-hot virial phase at log ( T/ K) = 6 . 33 +0 . 03 − 0 . 02 , a hot super-virial phase at log ( T/ K) = 6 . 88 +0 . 08 − 0 . 07 is required. Furthermore, we present observations of five fields within 5 degrees of the primary field. Their spectra also… 



Statistical analysis of measurement error models and applications : proceedings of the AMS-IMS-SIAM Joint Summer Research conference held June 10-16, 1989, with support from the National Science Foundation and the U.S. Army Research Office

The present work focuses on the development of a robust robustness approach to estimation in nonlinear errors-in-variables regression models for measurement error models, which have been developed in the context of functional and structural relationships.
