1997A&A...321..765B The neutral gas content of X-ray bright elliptical galaxies. Braine J., Henkel C., Wiklind T. Received 16 August 1995/Accepted 8 November 1996 Abstract. Sensitive CO observations are presented for a sample of elliptical galaxies which are luminous X-ray and weak far infrared (FIR) emitters. Only non-detections were obtained. The absence of detectable amounts of CO (this includes the previously `detected' prototypical galaxy NGC 4472) does not support those standard cooling flow scenarios in which dust grain sputtering reduces the FIR luminosity, while cooled down gas is forming a significant mass of dense molecular gas. Key words: galaxies: cooling flows - galaxies: individual: NGC 4472 - galaxies: ISM - galaxies: elliptical - radio lines: galaxies - X-rays: galaxies
