A high energy workshop held at the INAOE

Instituto Nacional de Astrofísica Optica y Electrónica

Tonantzintla, Puebla, México

October 9-11, 2000



This site contains the following information about the meeting:

  • SCOPE AND AIM

    The Compton Gamma-Ray Observatory provided a new insight into the high energy window of the Universe. The EGRET instrument left as legacy its Third Catalog of High Energy Gamma-Ray Sources, providing so far one type of persistent extragalactic gamma-ray sources -blazars- and one type of Galactic sources -pulsars. Most of the newly discovered objects are unidentified sources, with a clearly predominant Galactic population. Are all these radio-quiet pulsars, like Geminga, or is there a novel type of emitter, awaiting identification?

    In spite of the limited angular resolution provided by EGRET and COMPTEL, there is still much to learn about unidentified sources: correlation studies, multiwavelength observations and theoretical work can provide valuable clues, specially if these efforts are carried out in a coordinated manner.

    The aim of this workshop is to gather most of the experts on the subject, including observational astronomers specialized in other regions of the electromagnetic spectrum, in an effort to address the question of the Nature of Galactic high-energy gamma-ray sources, both from the theoretical and observational perspective, and elaborate schemes for future identification studies which can make use of existing and forthcoming facilities.

  • DATES and VENUE

    The workshop will take place from October 9 to 11, 2000, in the Instituto Nacional de Astrofísica Optica y Electrónica (INAOE), at Tonantzintla, site of the former Mexican Astrophysical Observatory. In the last five years INAOE has organized several international conferences, including an IAU Latin-American Regional Meeting.

    Tonantzintla is located 5kms South of the prehispanic city of Cholula and 12kms SW from the city of Puebla. With two million inhabitants, Puebla is one of the major cities in Mexico, both in size and in cultural life. Puebla is located 120 kms East of Mexico City. A bus service links Mexico City airport with Puebla, every 30 minutes, ensuring easy travel to INAOE visitors.

  • Accomodation
    At this stage participants are suppossed to have done their hotel arrangments, either through us or by themselves. We have reserved rooms at the hotel Posada Señorial in Cholula, some 5kms away from the conference site at Tonantzintla. The rates are 345 pesos for an occupant on a single room, 220 pesos for each occupant of a double room, including breakfast. If you have not arranged your accomodation you can contact us, or contact the hotel directly at +52(2)2470059, asking for Beatriz Tlahuisca (mention the workshop).

    Other hotel options are available, although practically all in Puebla, of which we recommned:

  • Cacaxtla
    For Tuesday afternoon, the LOC is organizing a visit to the archeological site of Cacaxtla, one of the few Mexican sites with prehispanic paintings, apart from the ruins from the Olmecas-Xicalancas, dated between 600 and 900 AD. It is located some 30 kms NW from INAOE and getting there (by bus) should take around 30 mins. Soledad del Rio has a splendid page about
    Cacaxtla.


  • Fee
    A registration fee of 100 US dollars will be charged (75 USD for students) to all participants. This is to be paid cash in pesos or US Dollars when registering. The fee covers the proceedings, welcome cocktail (at Hotel Posada Señorial), Tuesday tour to Cacaxtla, coffee breaks, transport between hotel Posada Señorial and INAOE (+ help us with extra expenses).

    There will be early registration at the hotel Posada Señorial from Sunday afternoon (opening a couple of hours before the welcome cocktail).

  • Lunch
    Note that the town of Tonantzintla has no restaurant. Lunch will be organized at the workshop site on Monday to Wednesday. The cost is 12 US dollars per lunch and tickets need to be acquired at the registration desk. Menu includes vegetarian dishes.


  • Transport between hotel and INAOE
    We will provide transport between the hotel Posada Señorial ONLY and the conference site. Taxis -free of charge- from the company "Taxi-Fam" will be available at the hotel at 8:30am (at 8:20am on Monday). We recommend these if you want to move around. Taxi-Fam phone number is 2445900 and 2337799.

    If you are staying somewhere else (except Villas, which is in walking distance from Posada Señorial), i.e. in Puebla, it is convenient to rent a car. A drive between Puebla and Tonanztintla takes under 30 mins.

  • GETTING TO PUEBLA, CHOLULA AND TONANZTINTLA
    The main gateway to the country is Mexico City airport, linked to Puebla by a comfortable bus service that runs every 30 minutes. Puebla has its own international airport, with daily flights to and from Dallas and Houston. If you are flying to Mexico City or directly to Puebla, follow these
    instructions, and have a look to the map.

  • Tourism
    If you plan to spend some extra days around, you can check the Starburst local guide to Tonantzintla, Puebla and suroundings, Sole's page on Mexico or a more formal web guide of the country in Mexico-travel.


  • Money
    The Mexican currency is the peso represented by the symbol N$. The present correct exchange rate with the U.S. dollar is about N$ 9.6 = 1 USD but this changes with time. You can check the latest conversion factor at CNN.com.
    Please make sure you have some pesos with you BEFORE leaving the Mexico City airport, where there are plenty of currency exchange offices. Once in Mexico, not all places take US dollars or traveller's checks. Foreign credit cards are accepted in major restaurents, stores and hotels.

    Best exchange rates are found in CASAS de CAMBIO (exchange houses) open only on weekdays, usually from 9 am to 5 pm. Most banks open only on weekdays, also from 9 am to 5 pm. The airport has 24 hour money exchange counters. USA cash or travellers checks are easier to change into pesos than other types of currency.


  • Climate
    The region of Puebla, Cholula and Tonantzintla is located at an altitude of 2200 meters (7100 feet). There is usually no rain at this time of the year. The average temperature varies from some 20 C (68 F) in the daytime to about 5 C (41 F) in the night/morning. Ocassionally the night time temperature can drop to about the freezing point. Note that the air is thin and dry.


  • Language
    Spanish is the official language in Mexico. Because Puebla is not overly frequented by tourists, very few people speak English. We advise you to have a good dictionary and a phrasebook when you venture out.


  • Health
    Come prepared if you have a medical condition that can be affected by high altitude. The main health risk is traveller's diarrhea and precautions can be taken to reduce this risk. Please refer to a good travel guide for details.


  • Food
    Mexican cuisine is among the best in the world, but those visiting for the first time should take some precautions. There are some spicy sauces (salsas picantes) which could be very aggressive to unaware mouths: before adding any sauce to your food, try a small amount of it on a piece of bread. Also, to avoid traveller's diarrhea (or any other stomach disease), do not drink tap water and do not eat raw fruits or vegetables without skin. Drink only bottled water.


  • Sponsor
    This event is supported by CONACyT: Consejo Nacional de Ciencia y Tecnología. A limited amount of funding assistance is available.
